You are looking to find if the average selling price of a home in an area is greater than $350,000. You look at 50 homes in the area and compute the average price of the 50 homes to be $350,000 with a standard deviation of $25,000. At the 5% significance level we determine if the null hypothesis should be rejected. Give the null and alternative hypotheses.
