He had a golf equipment lab test a low compression ball by having a robot swing his club 9 times at the required speed. Data from the test in the previous problem/question resulted in a sample mean of 206.8 yards with a sample standard deviation of 5.4 yards Assuming normality, carry out a hypothesis test at the 0.05 significance level and determine whether the ball meets the golfer's requiremen Use the partial t-table above. O t= -3.78, Critical value = 1.860. Reject the null hypothesis. O t=1.86. Critical value = 3.78. Reject the null hypothesis. O t= -1.86, Critical value = 3.78. Reject the null hypothesis. O t=3.78, Critical value = 1.860. Reject the null hypothesis
