The accompanying data represent the running times of files produced by two motion-picture companies. Assume that the running-time differences are approximately normally distributed. Construct a 90% confidence interval for Company 11 Time (minutes) 105 89 118 91 117 Click here to view page 1 of the table of critical values of the F-distribution, for alpha= 0.05. Click here to view page 2 of the table of critical values of the F-distribution, for alpha = 0.05. 100 102 The confidence interval is 99 83 (Round to three decimal places as needed.) 98 174 89 C If a 90% confidence interval for μ₁ −μ were created, should it be assumed that o2 = 0²?
