Jack tells Jean that his average drive of a golf ball is 275 yards. Jean is skeptical, she thinks he has overstated is driving distance and asks for substantiation. So Jack takes a random sample of 25 of his drives. The mean of this sample is 264.4 yards.
His driving distance is known to be normally distributed with a population standard deviation of 20 yards.
Test Jean's claim that Jack's driving distance is less than 275 yards at a 0.05 significance level.
Would you write the null hypothesis as follows:
