9.2 ± 3.4
b.

8.4 ± 1.1

Solution:

A test of H0: µ = 7 versus H1: µ ≠ 7 does not reject the null hypothesis at the 5% level. If calculated using the same sample data, which of the following is a possible 95% confidence interval for the population mean?

Answer
c.

There is not enough information to determine anything about a 95% confidence interval.

Here answer is optiona c is correct because we know that for finding the confidence interval we have requaerd the value of samples mean samples, standard deviations, samples size and level of significance but here those value are not present hence option C is correct

7. Suppose you are testing H0 : µ = 10 vs H1 : µ 6= 10. The sample is small (n = 5) and the data come from a normal population. The variance, σ 2 , is unknown. (a) Find the critical value(s) corresponding to α = 0.10. (b) You find that t = −1.78. Based on your critical value, what decision do you make regarding the null hypothesis (i.e. do you Reject H0 or Do Not Reject H0)?
