1. Simple hypothesis testing with a real example (12 points) Suppose that Y is normally distributed with mean [1: and standard deviation of a. We set the null hypothesis such that the population mean of Y, denoted by p, equals 0. In this section1 we will manually compute sample mean, denoted by r. compute the standard error of n, and calculate the t-statistic to conduct a hypothesis test at the 5% signicance level. We then will compare our computations with the interceptponly regremion result. |*
