A local tennis pro-shop strings tennis rackets at the tension (pounds per square inch) requested by the customer. Recently a customer made a claim that the pro-shop consistenty strings rackets at lower tensions, on average, than requested. To support this claim the customer asked the pro shop to string 10 new rackets at 50 psi. Upon receiving the rackets, the customer measured the tension of each and calculated the following summary statistics x= 48 psi, s=25 psi. In order to conduct the test, the customer selected a significance level of a=0.01. interpret this value OA. The smallest value of a that you can use and still reject H, is 0.01. OB. There is a 1% chance that the sample will be biased. OC. The probability of making a Type Il error is 0.99. OD. The probability of concluding that the true mean is less than 50 psi when in fact it is equal to 50 psi is only 0.01.
