Using the heights_weights data, complete the following exercises.

a) What do we need to assume about the distribution of height in the population in order to use Z or t score methods in constructing confindence interveals or testing hypotheses?

b) Calculate the p-value of the sample mean if our null hypothesis is the mean is 5’10″ (70 inches)

c) Using the χ2-test for the independence of two discrete random variables, test the hypothesis that hieght and weight are indpendent. (Hint: the data is continuous. the χ2-test requires the data to be categorical. How might you make a continuous random varaible categorical?)
