It seems like there might be a typo in the question. Let's assume the null hypothesis is that the population mean (μ) is equal to 10: H0: μ = 10 H1: μ ≠ 10 Now, we are given a significance level (α) of 0.10. Since this is a two-tailed test (because the Show more…

Suppose you are testing Ho: p=0.36 versus Ha: p<0.36. If the sample size is 30, and the significance level is 10%, what is the critical value of the test? (round to 2 decimal places)

Determine the critical value or values for a one-mean z-test at the 20% significance level if the hypothesis test is left-tailed (Ha: μ < μ0). z0.8 - 0.842, z0.4 - 0.253, z0.2 - 0.842, z0.1 - 1.282, z0.05 - 1.645.
