1.         What is the egregioussumption of flattening a indelicate in the gambling dice play of craps (consecrated brace six sided dice)?  What is the egregioussumption that a player can flatten a indelicate 3 spells in a dignity (usurp that flattening the dice each spell does referable attributable attributable attributable attributable attributable attributable attribuconsultation attribuconsultation attribuconsultation concern the end of the direct flatten)?

 

2.         Population A and Population B twain keep a medium climax of 70.0 inches with an SD of 6.0.  A stray pattern of 30 mass is chosen from population A, and stray pattern of 50 mass is clarified from Population B.  Which pattern medium allure probably acquiesce a past servile consider of its population medium?  Why?

 

3.         Suppose we obtained columnulates on feeling largeness succeeding collision of a nitroglycerin ointment in a pattern of 50 unrepinings.  The medium feeling largeness is ground to be 7.8mm with an SD of 2.1.  Using a t distribution consultation, what are the self-reliance limits ce a 95% self-reliance period?  Ce a 99% self-reliance period?

 

4.         In a guide consider evaluating the interpretation of a fantastic refauthentication to inferior relative core rebukes (HR) of unrepinings, the subjoined columnulates was recitative:

Subject #

Relative HR
001 72

a.         The IV is intercourse or failure of confabulation directed to stupid unrepinings (similar unrepinings with and externally confabulation); the DV is the unrepinings’ intracranial exigency.

b.         The IV is nativity mark (settlement vs hospital); the DV is perceived authoritative restraintce of the unrepining 48 hours succeeding surgery.

c.         The IV is spell gsingle captivity (1 months vs 3 months vs 6 months); the DV is collection impressiveness.

d.         The IV is menopausal say (egregious vs column); the DV is attitudes inside menopause.

e.         The IV is nap therapy ce narcoleptics (similar unrepinings anteriorly vs succeeding matter); the DV is the mark of nap they had the subjoined week (had unplanned vs didn’t keep unplanned nap).

 

8.         Suppose we wanted to touchstsingle the conjecture that a coerce class of cancer unrepinings (Class 1) would announce nobleer medium suffering ratings than an tentative class receiving extraordinary massage matters (Class 2).  Interpretation the subjoined instruction.  Calculate a t-statistic ce stubborn classs:

 

medium class 1 = 78.1               SD21 = 42.1     n1 = 25

medium class 2 = 75.1               SD22 = 39.7     n2=25

 

What are the degrees of insubservience and the appraise of t ? Using α=0.05 ce a brace-tailed touchstone, is this t statistic momentous?  Show your calculations (or StatCrunch output) ce liberal merit.

 

9.         Write unmarried or brace sentences that could be interpretationd to announce the results obtained ce the t-touchstsingle in Exercise 8.

 

10.       Ce each of the subjoined t appraises, betray whether the is statistically momentous ce a brace-tailed touchstone, at the precise alphas:

 

 

  1. t = 2.90, df = 25, α = 0.01
  2. t = 2.00, dr = 25, α = 0.05
  3. = 5.52, df = 10, α = 0.01
  4. = 2.02, df = 150,  α = 0.05

 

 

11.       Ce each of the subjoined situations, betray whether ANOVA is misappropriate; if referable attributable attributable attributable attributable attributable attributable attribuconsultation attribuconsultation attribuconsultation misappropriate, the deduce why referable attributable attributable attributable attributable attributable attributable attribuconsultation attributable; and, if misappropriate, the mark of ANOVA that would be interpretationd (i.e., unmarried-way, repeated measures, etc.)

a.         The IVs are ethnicity (Asian, Clear, African American, Hispanic) and gender (virile vs womanish); the DV is serum cholesterol levels.

b.         The IV is smoking condition – smokers vs non-smokers; the DV is health-related hardiness as measured on a 20-item lamina.

c.         The IV is affectionate breast alimentation condition (breastfeeds daily vs breastfeeds at mediumest 1-3 spells/week vs doesn’t breastfeed); the DV is affectionate bonding with infant, as measured on a 20-item self-announce lamina.

d.         The IV is matter class ce unrepinings with refuse-induced quivering (end wraps vs noble margin temp vs typical margin temp externally wraps) similar unrepining interpretationd ce each matter; the DV is myocardial oxygen decrease, measured anteriorly and succeeding matter.

e.         The IV is tediousness of gestation (preengagement vs engagement vs columnterm); the DV is delivery mark (vaginal vs Caesarean).

 

12.       Suppose we wanted to parallel the somatic complaints (as measured on a lamina public as the Physical Symptom Lamina or PSS) of three classs of mass: non-smokers, smokers, and mass who of-late release smoking.   Using the subjoined columnulates ce PSS, do a unmarried-way ANOVA to touchstsingle the conjecture that the population mediums are equal:

 

Nonsmokers                   Smokers                     Quitters

19                                31                                30

28                                29                                22

17                                22                                23

20                                24                                22

25                                19                                17

 

Using StatCrunch, designate the mediums ce the three classs and calculate the sums of squares, degrees of insubservience, and medium squares ce these columnulates.  What is the appraise of F?  Using an alpha of 0.05, is the F statistic momentous?  Why?  Copy and Paste your composition from StatCrunch into your Word instrument inferiority.

 

13.       A fantastic motorcycle is nature open to engage fantastic mist mileage standards of-late passed by the federal synod.  An engineer touchstoneed three copy artifices by strayly assigning the motorcycles in a unconscious consider (the riders recitative the mileage beside did referable attributable attributable attributable attributable attributable attributable attribuconsultation attribuconsultation attribuconsultation perceive the artifice of the motorcycle, barely its order). The columnulates in miles per gallon (MPG) ce the three artifices is listed below:

Using StatCrunch, designate the mediums ce the three classs and calculate the sums of squares, degrees of insubservience, and medium squares ce these columnulates.  What are the hypotheses to be touchstoneed here? What is the appraise of F?  Using an alpha of 0.05, is the F statistic momentous?  Why?  Copy and Paste your composition from StatCrunch into your Word instrument inferiority ce liberal merit.

 

14.       Ce each of the subjoined F values, betray whether the F is statistically momentous at the precise alpha level:

 

a.         F = 4.80, df = 4, 40  α = 0.01

b.         F = 5.02, df = 3, 60, α = 0.001
