The mean of a population is assumed to be 5000. However, it is also believed the mean is not 5000. A sample of size 49 from the population is considered. Assume a calculated sample mean of 5100 and a standard deviation of 100. At the 5% significance level we will determine if the null hypothesis will be rejected. Give the null and alternative hypotheses.

Give the conclusion. Reject the null since the test statistic is in the rejection region and the p value is less than the significance. O Reject the null since the test statistic is in the rejection region and the p-value is greater than the significance. Fail to reject the null since the test statistic is not in the rejection region and the p-value is less than the significance.. O Fail to reject the null since the test statistic is not in the rejection region and the p-value is larger than the significance.
