- Transport trade association conducted a survey of their members to determine what they felt were the important issues to be discussed with the management. The survey results showed that 74% felt that the job security was the important issue, while 65% felt that salary increment was an important issue. Of those who felt salary increment was an important issue, 60% also felt that job security was an important issue. What percentage of the members felt that both job security and salary increment were important? What percentage of the members felt that at least one of these two issues was important?The Consumer Reports National Research Center conducted a telephone survey of 2000adults to learn about the major economic concerns for the future (Consumer reports,January 2009).

You ask 100 students (randomly sampled) how much they'd be willing to pay to fund community supervision programs over the current cash bail system. There is another question that asks students if they believe reforming cash bail is a serious issue. Select all correct answers. The response variable is a student's belief that cash bail needs to be reformed. The reponse variable is the amount of tax a student is willing to pay to cover community supervision costs. Students answer yes or no to the question of whether they believe cash bail reform should occur. This means the samples are independent. Students answer yes or no to the question of whether they believe cash bail reform should occur. This means the samples are dependent.

- In 2011 home prices and mortgage rates dropped so low that in a number of cities the monthly cost of owning a home was less expensive than renting. The following data show the average asking rent for 10 markets and the monthly mortgage on the median priced home (including taxes and insurance) for 10 cities where the average monthly mortgage payment was less than the average asking rent (The Wall Street Journal, November 26–27, 2011).Click on the datafile logo to reference the data. Enter negative values as negative numbers. a. Develop the estimated regression equation that can be used to predict the monthly mortgage given the average asking rent (to 2 decimals).The regression equation is:Mortgage ($) = + Rent ($)Transport trade association conducted a survey of their members to determine what they felt were the important issues to be discussed with the management.
