Twо types оf flаres аre tested аnd their burning times (in minutes) are recоrded. The summary statistics are given below.Brand X Brand Yn = 45 n = 50 x-bar = 20.4 min x-bar = 16.1 mins = 1.5 min s = 0.9 min A) Use a 0.05 significance level to test the claim that the two samples are from populations with the different means. (14pts) Perform the following steps: (3pts) Step 1: Requirements (2pts) Step 2: (3pts) Step 3: Test statistic: (round to 3 decimal places) (3pts) Step 4: Critical value (round to 3 decimal places) (2pts) Step 5: Critical value method (1pt) Step 6: Conclusion B) Construct a 95% confidence interval for the difference between the burning mean times of two types of flares using the following steps. (6pts) Perform the following steps: (1pt) Command: (2pts) Information for the command: (1pt) CI: (round to 1 decimal place) (2pts) Does it appear there is a difference between the two mean times of two types of flares? Explain C) (2pts) Are the hypothesis test and the confidence interval giving the same result? Explain
