Question
Consider the following hypothesis test.
H0: μ = 18
Ha: μ ≠ 18
A sample of 48 provided a sample mean x = 17 and a sample standard deviation s = 4.9.
(a)Compute the value of the test statistic. (Round your answer to three decimal places.)
___________________.
(b)Use the t distribution table to compute a range for the p-value.(multiple choice)
- p-value > 0.200
- 0.100 < p-value < 0.200
- 0.050 < p-value < 0.100
- 0.025 < p-value < 0.050
- 0.010 < p-value < 0.025
- p-value < 0.010
(c) At α = 0.05, what is your conclusion?(mulitiple choice)
- Do not reject H0. There is sufficient evidence to conclude that μ ≠ 18.
- Reject H0. There is insufficient evidence to conclude that μ ≠ 18. - Do not reject H0. There is insufficient evidence to conclude that μ ≠ 18.
- Reject H0. There is sufficient evidence to conclude that μ ≠ 18.
