To test H0: = 4.5 versus H1: > 4.5, a simple random sample of size

Question:

To test H0: µ = 4.5 versus H1: µ > 4.5, a simple random sample of size n = 13 is obtained from a population that is known to be normally distributed.

(a) If x̄ = 4.9 and s = 1.3, compute the test statistic.

(b) Draw a t-distribution with the area that represents the P-value shaded.

(d) If the researcher decides to test this hypothesis at the α = 0.1 level of signiﬁcance, will the researcher reject the null hypothesis? Why?
