Question

Consider the following hypotheses:
H₀: μ = 30
H_A: μ ≠ 30

The population is normally distributed. A sample produces the following observations:

33

26

29

35

31

35

31

At the 10% significance level, what is the conclusion?

a) Reject H₀ since the p-value is greater than α.

b) Reject H₀ since the p-value is smaller than α.

c) Do not reject H₀ since the p-value is greater than α.

d) Do not reject H₀ since the p-value is smaller than α.

Interpret the results αα = 0.1.

a) We conclude that the sample mean differs from 30.

b) We cannot conclude that the population mean differs from 30.

c) We conclude that the population mean differs from 30.

d) We cannot conclude that the sample mean differs from 30.
