The treadmill motors are purchased from an outside vendor. Currently, the company is considering which motor to include inits new treadmill series. Three potential suppliers have been identified. The company has decided to make its decision based on how long a motor operates at a high level of speed and incline before it fails.A random sample of 10 motors of each type is selected, and each motor is tested to determine how many minutes (rounded to the nearest minute) it operates before it needs to be repaired.

a. At the a = 0.01 level of significance, is there a difference in the average times before failure for the three different suppliers' motors? Identify the hypotheses for the test. Choose the correct answer below. O A. Ho: H1 = H2=H3 Hạ: All of the population means are different O B. Ho: H = H2=H3 Hạ: At least two of the population means are different OC. Ho: H, * H2 # H3 Hạ: At least two of the population means are equal O D. Ho: H, + H2 #H3 Hạ: All of the population means are equal Find the test statistic F. F= (Round to two decimal places as needed.) Now find the p-value. p-value = (Round to three decimal places as needed.)
