A random sample of 15 customers in two different banks were selected and their wait times (in minutes) are given below. Use this data to complete parts (a) through (d). Bank A 6.11 3.11 4.43 6.01 0.38 5.03 6.51 4.29 5.51 3.03 5.11 4.77 2.34 5.99 8.06 5.69 8.64 3.83 8.18 8.29 6.66 5.73 3.98 6.14 9.83 5.56 Bank B 3.58 3.74 9.68 10.56 a. Is there evidence of a difference in the variability of the waiting time between the two banks? (Use α=0.01.) Determine the hypotheses. Choose the correct answer below. A. H₂: 0²₁=0₂ A. H₁:0² #0² OC. Ho: 0202 H₁: 0} <0² Compute the FSTAT test statistic. FSTAT = (Round to two decimal places as needed.) O B. Ho: 0² 50² H₁:0² > 0² D. Ho: o #0² H₁:0² = 6²
