Consider the hypothesis statement: Ho: μ = 62 vs Ha: μ ≠ 62. Given that n = 48, x̄ = 25, s = 27, and α = 0.05, we can use the critical value table to find the critical value. With α = 0.05 in the right tail of the distribution, the critical value is 1.96.
Calculate the appropriate test statistic:
The test statistic is (x̄ - μ) / (s / ∑n).
Determine the appropriate critical value:
The critical value is 1.96.
There is evidence to suggest that the population mean is different from 62.
