1. Treat thePatients dataset (Excel)as a sample from a larger population.Assuming that the total charges variable is normally distributed, use a one-tail t test of hypothesis ( = 0.05) for the mean ( unknown) to test the hypothesis that the population mean total charges is greater than $10,000.Make sure you define the null and alternate hypotheses.
2. Using the pooled variance t-test for the difference between two means, at the 0.05 level of significance, is there evidence that the mean age for male patients is different from the mean age for female patients?Be sure to provide the null and alternate hypotheses.
3. Showing yourwork is required, not just providing answers without showing how you arrived at them.
