The following four questions will be based on this problem. The mean of a population is assumed to be 12.1. However data suggests the mean can be greater than 12.1. A sample of size of 50 from the population is considered. Assume a calculated sample mean of 12.2 and standard deviation of 0.2. At the 5% significance level we will determine if the null hypothesis should be rejected. Give the null and alternative hypothesis for this problem. Null: Population mean is equal to 12.1, Alternative: Population mean is less than 12.1 Null: Population mean is equal to 12.1, Alternative: Population mean is greater than 12.1 Null: Population mean is equal to 12.2, Alternative: Population mean is less than 12.2 Null: Population mean is equal to 12.2, Alternative: Population mean is greater than 12.2
