Multiple Choice


1. Based on sample data, the 95% confidence interval for the population proportion is 0.75 < p < 0.85. If the 5% level of significance were used in testing the hypotheses Ho: P=0.74 vs p =/ (slash through the equal sign) 0.74, the null hypothesis is

a. would not be rejected
b. would be reject
c. would not be rejected at the 10% significance level
d. would become ho p =/ 0.74

2. for a 90% confidence interval of the population proportion based on a sample of n = 121 and p=0.67, the margin of error is:

A. e=0.003
b e=0.043
c e=0.14
d e=0.07
