A government official estimates that the mean time required to fill out the long form of the United States Census follows a distribution which is approximately normal with mean 36 minutes. A random sample of 16 people who were given the long form took a sample mean time (x-bar) = 40 minutes with sample standard deviation (s) = 10 minutes. perform a upper-tail test to  (a) Find the critical value of the t-statistic with a 10% level of significance. (b) Find the t-test statistic from the sample data (c) Find the p-value
