A. give the null and alternative hypotheses

B Give the critical values of the test

C. Give the test statistic

D. Give the p value

E. Give the type of error you could have made

Assuming the proportions found in problem 2 is the true proportion of all voters in favor of sports gabling test the hypothesis’s that the proportion of students in favor of sports gambling is higher at the a=0.05 significance level. From a recent survey of 500 students. 178 were in favor of sports gabling

A. give the null and alternative hypotheses

B Give the critical values of the test

C. Give the test statistic

D. Give the p value

E. Give the type of error you could have made

Answer 1

2)

A)

null Hypothesis:               Ho:		p	=	0.325
alternate Hypothesis:    Ha:		p	>	0.325

B)_ critical values of the test Z=1.645

C) test statistic =1.48

D)p value =0.0694

E) as we fail to reject null hypothesis ; this may lead to type II error
