Question 1: The following data set shows the amount of timeconsumers have to wait on hold, in minutes, before talking to a customerservice representative. Compute by hand the mean and standard deviation.Take a picture, scan your work, or type up a detailed solution. Explain whatthe mean and standard deviation tell you about this data set.9.148.148.748.779.268.106.133.109.137.26Question 2: The distribution of the ages of a nation’s population has a stronginfluence on economic and social conditions. The following table shows theage distribution of U.S. residents in 1950 and the projected distribution in2075, in millions of people.Because the total population in 2075 is much larger than the 1950population, comparing percent in each age group is clearer then comparingcounts. Make a table of the percent of the total population in each age groupfor both 1950 and 2075. Use excel to enter the original data and to computethe percentages.Using excel create two histograms with a vertical scale in percents forthe 1950 and 2075 population data.Insert the histograms into a word document and discuss the mainfeatures of each histogram and compare and contrast them.Upload both your excel and word document
