Use the information below to answer Questions 1 through 3.

Given a sample size of 34, with sample mean 660.3 and sample standard deviation 104.9, we

perform the following hypothesis test. Since n>30, this is a Z test.

Null Hypothesis Ho : p= 700

Alternative Hypothesis Ha : p * 700

1. What is the test statistic? What is the p-value?

2. At a 5% significance level (95% confidence level), what is the critical value(s) in this

test? Do we reject the null hypothesis?

3. What are the border values of jc- between acceptance and rejection of this hypothesis?
