A random sample of 20 retirees in 2019 was collected and the age in years at which they retired was recorded in the data set "Retirement Age" Using o - 0.01, is there sufficient evidence to conclude the average age of 2019 retirees is different from the FRA of 66.5 years? Conduct a full hypothesis test by following the steps below Enter an answer for each of these steps in your document. a) Define the population parameter in context in one sentence. b) State the null and alternative hypotheses using correct notation. c) State the significance level for this problem. d) Create a frequency histogram and a box plot of the sample data and copy these into your document. e) Based on the graphs you created in 4(d), do you believe that the population of age of retirees that this sample came from is normally distributed? State your response with a valid reason in one to two complete sentences. f) Check the three that allow you to calculate the test statistic using one sentence for each condition. g) Calculate the test statistic "by-hand." First, calculate the sample mean and sample standard deviation using StatCrunch and do not round these values. Next, show the work necessary to obtain the test statistic by typing all your steps and providing the resulting test statistic. Do not round anything during the calculation. Then, round the test statistic to three decimal places after you complete the calculation
