To better understand the size of a household for AJ Davis’s credit customers we used a table of descriptive statistics, frequency table, and a bar chart. Descriptive Statistics: Size Variable Mean SE Mean StDev Variance Minimum Q1 Median Q3 Size 3.420 0.246 1.739 3.024 1.000 2.000 3.000 5.000 N for Variable Maximum Mode Mode Size 7.000 2 15 Tally for Discrete Variables: Size Size Count CumCnt 1 5 5 2 15 20 3 8 28 4 9 37 5 5 42 6 5 47 7 3 50 N= 50 This information tells us that the mean, or average, household size of the credit customer is 3.42. The median, or middle, household size is 3. There is a standard deviation of 1.739. As can be seen in the bar chart and the frequency table, the mode, or most frequent occurring household size, is 2 with 15 out of the 50 households being this size.
b. The true population proportion of customers who live in an urban area exceeds 40% c. The average (mean) number of years lived in the current home is less than 13 years d. The average (mean) credit balance for suburban customers is more than $4300 I have been assigned to analyze the speculated data listed above by performing hypothesis test for each of the above situations (using the Seven elements of a Test Hypothesis with a=.05) in order to see if there is evidence to support my manager’s beliefs in each case (a-d), explain my conclusion in simple terms, compute the p-value with the interpretation, follow up with computing 95% confidence intervals for each of the variables described in a. b. c. d. along with interpreting these intervals. This paper will also include an Appendix with all the steps in hypothesis testing, as well as the confidence intervals and Minitab output In order to understand how hypothesis testing is done it is important that you know the elements of the Test of Hypothesis, and what each step means. The Seven elements of a Test of Hypothesis are: 1. Null
