The mean of a population is assumed to be 75. However data suggests the mean can be less than 75. A sample of size 100 from the population is considered. Assume a calculated sample mean of 60 and a standard deviation of 10. At the 1% significance level we will determine if the null hypothesis should be rejected. Give the null and alternative hypothesis.
