please show all the work so I know how to do it. and please do it asap i need help soon

1) Recall the data on male fighter pilots and males from the general population from Homework 7. In the table below, we have the heights of 12 male fighter pilots and 14 males from the general public in inches. Both samples were randomly selected. The data file Pilot/General Heights is also available in our StatCrunch group. Assume the population of heights for fighter pilots and the general public follow normal distributions. Fighter Pilot Heights General Population Heights 65.3 68.9 67.5 67.4 68.3 71.4 66.6 71.2 63.7 73.0 69.6 69.3 67.7 73.2 64.9 64.9 68.0 73.1 64.8 74.2 68.2 81.2 66.2 62.7 65.2 63.8 Previously, we tested if the standard deviation of fighter pilot heights were less than 3 inches. Now, we will not assume the standard deviation of all males is 3 inches and will instead test if we have enough evidence to suggest that the standard deviation of fighter pilot heights is less than the standard deviation of the heights of males in the general population based only on the data given above. Use a = 0.05 to conduct the F test. Be sure to show each step of the test. Before beginning the test, in words and in the context of the problem, list the parameters of interest with the associated symbol
