Data is collected to test the hypotheses.
Ho : p= 0.35 vs Ha: p ( can not equal ) 0.35
1. You obtain a p-value of 0.021. Which of the following is true ?
a) A 95% confidence interval for p will include the value 0.35
b) A 99% confidence interval for p will include the value 0.35
c) A 90% confidence interval for p will include the value 0.35
d) None of the confidence intervals listed above will include the value 0.35
2. We calculated a 90% confidence interval for p to be (0.36, 0.67 ) and want to test the following:
Ho: p= 0.35 vs Ha: p ( can not equal) 0.35
a) If the above confidence interval is used to test the given hypotheses, what would the statistical decision be ?
b) What would the level of significance of the hypothesis test be?
