The total costs of housing for homeowners might include mortgage payments, property taxes, and utility costs (water, heat, electricity). An economist selected a sample of 20 homeowners in New England and then calculated these total housing costs as a percent of monthly income, 5 years ago and now. The information is reported below. Is it reasonable to conclude the percent is less now than 5 years ago?

It is believed that large doses of acetaminophen (the activeingredient in over the counter pain relievers like Tylenol) may cause damage to the liver. A researcherwants to conduct a study to estimate the proportion of acetaminophen users who have liver damage. Forparticipating in this study, he will pay each subject $20 and provide a free medical consultation if the patienthas liver damage.(a) If he wants to limit the margin of error of his 98% confidence interval to 2%, what is the minimumamount of money he needs to set aside to pay his subjects?(b) The amount you calculated in part (a) is substantially over his budget so he decides to use fewer subjects.How will this affect the width of his confidence interval?Sleep Late, a large hotel chain, has been using activity-based costing to determine the cost of a night’s stay at their hotels. One of the activities, “Inspection,” occurs after a customer has checked out of a hotel room. Sleep Late inspects every 10th room and has been using “number of rooms inspected” as the cost driver for inspection costs. A significant component of inspection costs is the cost of the supplies used in each inspection Mary Adams, the chief inspector, is wondering whether inspection labor-hours might be a better cost driver for inspection costs. Mary gathers information for weekly inspection costs, rooms inspected, and inspection labor-hours as follows: Q.Plot the data and regression line for rooms inspected and inspection costs. Plot the data and regression line for inspection labor-hours and inspection costs. Which cost driver of inspection costs would you choose? Explain.

- E. On a survey, why might you want to measure income at the ratio rather than ordinal level? Why might you want to measure income at ordinal rather than ratio level? Consider the kinds of claims you might want to make from your data and how you might gather the most valid data. Give a concrete example why each might be preferred (ratio rather than ordinal, ordinal rather than ratio), and make sure it is evident from your answer that you fully understand levels of measurement.An agent for a residential real estate company in a suburb located outside a major city has the business objective of developing more accurate estimates of the monthly rental cost for apartments. Toward the goal, the agent would like to use the size of an apartment, as defined by square footage to predict the monthly rental cost. The agent selects a sample of 8 one-bedroom apartments and the data are shown. Complete parts (a) through (f).
