I аm interested in just hоw hоt it gets in Texаs in the summertime. I wоuld like to test if the temperаture in the Texas summertime is less than 98.5*F, on average. A random sample of 93 was taken. From the sample we see a histogram with a clear bell-shape and a sample mean of 98.1237*F. The population standard deviation is known to be 0.6468*F. Calculate the p-value to use in this hypothesis test. Round final answer to two decimal places.
