Hypothesis test for single mean
Consider the following hypothesis test:
Ho: μ ≥ 14
Ha: μ < 14
A sample of 64 provides a sample mean of 13 and a sample standard deviation of 4.
1. Determine the standard error of the mean.
2. Compute the value of the test statistic.
3. Conclude the p-value; and at 95% confidence, test the above hypotheses.
