Consider the hypotheses:
H₀:/μ= 100
H_A:/μ≠100
Given sample data with x = 82, s = 34.7, n = 15, and α = 0.05, answer the questions below.
a. What are the degrees of freedom for the t - test?
b. What are the critical values for the test? Round your answer to three decimal places. + -
c. What is the test statistic? Round your answer to three decimal places.
d. What is the appropriate decision and why?
Reject the null hypothesis because the test statistic falls within the critical values.
Reject the null hypothesis because the test statistic falls outside the critical values.
Fail to reject the null hypothesis because the test statistic falls within the critical values.
Fail to reject the null hypothesis because the test statistic falls outside the critical values.
