A researcher wants to determine the causal relationship among number of family members who are at least high school graduate (W), number of working family members (X), monthly gross income (Y), monthly expenditure (Z), and average monthly bank deposits (A). A random sample of 20 families was selected and the data on the variables were collected (see household.xslx). Consider the following path diagram: 1. Set-up the structural equations. Consider the R outputs from the conducted path analysis. 2. Identify the factors affecting the endogenous variables. Leave blank if variable is exogenous.

Murder was committed in an air-conditioned laboratory. Dr. Quincy, the medical examiner, was summoned to the scene of the crime. One of the first things he did was to take the temperature of the corpse. At 9:23 PM, he recorded the temperature to be 20.1oC and at 9:53 Pm to be 18.7oC. He further observed that the thermostat of the air-conditioning unit was set at 16oC. After gathering all pertinent data and analyzing them for sometime, he submitted a preliminary report stating that the victim was murdered between 7 PM and 8 PM. Was Dr. Quincy's report correct? At what approximate time did the victim die? Assume that the normal body temperature of a human being, alive and well, is 37oC.
A medical researcher wishes to try three different techniques to lower blood pressure of patients with high blood pressure. The subjects are randomly selected and assigned to one of three groups. Group 1 is given medication, Group 2 is given an exercise program, and Group 3 is assigned a diet program. At the end of six weeks, each subjectʹs blood pressure is recorded. Find the critical value F0 to test the claim that there is no difference among the means. Use α = 0.05. Group 1 Group 2 Group 3 11 8 8 12 3 12 13 2 4 15 5 4 9 4 9 8 0 6

Children in the United States account directly for $36 billion in sales annually. When their indirectinfluence over product decisions from stereos to vacations is considered, the total economic spendingaffected by children in the United States is $290 billion. It is estimated that by age 10, a child makes anaverage of more than five trips a week to a store . Suppose that you want to prove that children in yourcity average more than five trips a week to a store. Let represent the population mean number of timeschildren in your city make trips to a store. a. State the null and alternative hypotheses. b. Explain the meaning of the Type I and Type II errors in the context of this scenario. c. Suppose that you carry out a similar study in the city in which you live. Based on past studies, youassume that the standard deviation of the number of trips to the store is 1.6. You take a sample of 100children and find that the mean number of trips to the store is 5.47.
