Question 1: The following data set shows the amount of time consumers have to wait on hold, in minutes, before talking to a customer service representative. Compute by hand the mean and standard deviation. Take a picture, scan your work, or type up a detailed solution. Explain what the mean and standard deviation tell you about this data set.
Question 2: The distribution of the ages of a nation's population has a strong influence on economic and social conditions. The following table shows the age distribution of U.S. residents in 1950 and the projected distribution in 2075, in millions of people.
Because the total population in 2075 is much larger than the 1950 population, comparing percent in each age group is clearer then comparing counts. Make a table of the percent of the total population in each age group for both 1950 and 2075. Use excel to enter the original data and to compute the percentages.
Using excel create two histograms with a vertical scale in percents for the 1950 and 2075 population data.
Insert the histograms into a word document and discuss the main features of each histogram and compare and contrast them.
Conduct necessary analyses using SPSS so you can answer the questions listed in the exercise.
