Question

We are testing h0: μ = 32; versus ha: μ > 32. if x⎯⎯ = 36, s = 1.6, and n = 30, at α =0 .05, we should reject h0. assume that the population from which the sample is selected is normally distributed. group starts

O True
O False

Answer 1

The student's question is regarding whether to reject the null hypothesis based on given sample data and significance level for a right-tailed hypothesis test. However, without more information such as the Z-score and critical values, we cannot definitively answer the query.

Step-by-step explanation:

The student is asking if the null hypothesis (H0: μ = 32) should be rejected given a sample mean (x-) of 36, a sample standard deviation (s) of 1.6, a sample size (n) of 30, and a significance level (α) of 0.05. To determine whether to reject H0, a hypothesis test is conducted.

The test statistic is calculated using the sample mean, the population mean under the null hypothesis, the sample standard deviation, and the sample size to find the Z-score. After finding the Z-score, it is compared to the critical value for the right-tailed test at α = 0.05. If the Z-score is higher than the critical value, H0 should be rejected.

However, it is important to note that the question does not provide enough information to complete this calculation, such as the critical value or the Z-score calculated from the given data.
