Suppose you conduct a t -test for the null hypothesis H0: = 1,000 versus the alternative hypothesis

Question:

Suppose you conduct a t -test for the null hypothesis
H0:µ = 1,000 versus the alternative hypothesis
Ha: µ = 1,000, based on a sample of 17 observations.
The test results are t = 1.89, p-value = .038.
a. What assumptions are necessary for the validity of this procedure?
b. Interpret the results of the test.
c. Suppose the alternative hypothesis had been the two tailed
Ha: µ ± 1,000. If the t-statistic were unchanged, what would the p-value be for this test? Interpret the p-value for the two-tailed test.
