Question

QUESTION 1

1. Suppose a student guesses that 75% of RCSJ students have been to at least one professional sporting event in Philadelphia. She gathers data and finds that 189 of the 290 RCSJ students surveyed had been to at least one professional sporting event in Philadelphia. She would like to conduct a hypothesis test to see if her guess was reasonable. What is her parameter?

   	A.	true proportion of all RCSJ students who plan to go to at least one professional sporting event in the next year
   	B.	true proportion of all RCSJ students who have been to at least one professional sporting event in Philadelphia
   	C.	true proportion of all RCSJ students who have been to at least one professional sporting event in their lifetime
   	D.	true proportion of all RCSJ students who enjoy watching professional sports

QUESTION 2

1. Suppose a student guesses that 75% of RCSJ students have been to at least one professional sporting event in Philadelphia. She gathers data and finds that 189 of the 290 RCSJ students surveyed had been to at least one professional sporting event in Philadelphia. She would like to conduct a hypothesis test to see if her guess was reasonable. What is the comparison value in this problem (the value that would be in the null and alternative hypothesis)?

   	A.	75%
   	B.	290
   	C.	65.2%
   	D.	189

QUESTION 3

1. Suppose a student guesses that 75% of RCSJ students have been to at least one professional sporting event in Philadelphia. She gathers data and finds that 189 of the 290 RCSJ students surveyed had been to at least one professional sporting event in Philadelphia. She would like to conduct a hypothesis test to see if her guess ewas reasonable. Which value below represents the test statistic for this hypothesis test?

   	A.	-0.85
   	B.	-2.85
   	C.	-1.85
   	D.	-3.85

QUESTION 4

1. Suppose a student guesses that 75% of RCSJ students have been to at least one professional sporting event in Philadelphia. She gathers data and finds that 189 of the 290 RCSJ students surveyed had been to at least one professional sporting event in Philadelphia. She would like to conduct a hypothesis test to see if her guess was reasonable. At a 95% confidence level, what critical value would mark off the rejection region for this test?

   	A.	1.645
   	B.	1.96
   	C.	2.575
   	D.	3.85

Answer 1

1)true proportion of all RCSJ students who have been to at least one professional sporting event in Philadelphia

2) comparison value in this problem )A) 75%

3)

std error       =Se		=√(p*(1-p)/n) =		0.0254
sample proportion     p̂		x/n=		0.6520
test stat = z                =		(p̂-p)/Se=		-3.85

option D

4)

critical value would mark off the rejection region for this test = 1.96

option B
