Two types of flares are tested and their burning times (in minutes) are recorded. 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

Provide an appropriate response.In a survey, 26 voters were asked their ages. The results are shown below. 43  56  28  63  67  66  52   48  37   51   40    60   62 66  45  21  35  49  32  53   61   53   69   31   48   59a) Construct a frequency distribution to represent the data (with 5 classes beginning with a lower class limit of 20 and a class width of 10). Also state all the class midpoints and class boundaries (9pts) b) Construct a frequency histogram for the data. Determine the distribution shape of the data. Make sure to label all the axes (7pts) c) Construct a cumulative frequency distribution for the data. Then construct an ogive graph for the data. Make sure to label all the axes (10pts) d) Construct a frequency polygon for the data. Make sure to label all the axes (5pts) g) Construct a stem and leaf plot for the data (5pts) h) List the 5-number summary. Make sure to include the calculator command (4pts) i) Construct a box-plot for the data (5pts)

Find the indicated probability. (4pts)A tennis player makes a successful first serve 51% of the time. If she serves 9 times, what is the probability that she gets exactly 5 first serves in? Assume that each serve is independent of the others. Make sure to first define variable X, then calculate the probability Define variabale X=
