A t -test is conducted for the null hypothesis H0:µ= 10 versus the alternative hypothesis Ha: µ ≠ 10 for a random sample of n = 17 observations. The test results are
t = 1.174 and p-value = .1288.
a. Interpret the p -value.
b. What assumptions are necessary for the validity of this test?
c. Calculate and interpret the p -value, assuming that the alternative hypothesis was instead Ha: µ≠ 10.
