The U.S. Census Bureau publishes data on factory orders for all manufacturing, durable goods, and nondurable goods industries. Shown below are factory orders in the United States over a 13- year period ($ billion). First, use the data to develop forecasts for years 6 through 13 using a 5-year moving average. Then, use the data to develop forecasts for years 6 through 13 using a 5-year weighted moving average. Weight the most recent year by 6, the previous year by 4, the year before that by 2, and the other years by 1. Answer the following questions: a) What is the forecast for year 13 based on the 5-year moving average? b) What is the forecast for year 13 based on the 5-year weighted moving average? c) What is the MAD for the moving average forecast? d) What is the MAD for the weighted moving average forecast? e) Which forecasting model is better?

2. The U.S. Census Bureau publishes information on the ages of
married couples. Suppose we want to determine whether, in the U.S.,
the mean age of married men differs from the mean age of their
wives. A random sample of married couples is taken and their ages
are recorded. Perform a hypothesis test at the 0.05 level of
significance to determine if the mean age of husbands differs from
the mean age of their wives. (Hint: Fill in the Difference...

The U.S. Census Bureau collects data on the ages of married
people. Suppose that eight married couples are randomly selected
and have the ages given in the following table. Determine the 98%
confidence interval for the true mean difference between the ages
of married males and married females.
Let d=(age of husband)−(age of wife)d=(age of husband)−(age of
wife). Assume that the ages are normally distributed for the
populations of both husbands and wives in the U.S.
