This question set will use the following scenario that we saw on last week’s homework assignment: Scores on the Wechsler Adult Intelligence Scale- Third Edition (WAIS-III) are nationally standardized to be normally distributed with a mean of 100 and standard deviation of 15. A psychologist has a dataset containing the WAIS-III scores from a random sample of 50 adults who are members of a specific organization. They want to know if there is evidence that the mean WAIS-III score in the population of all members of this organization is greater than the known national mean of 100. In the sample of 50 adults, the observed sample mean was 105. When doing any hand calculations, show all work.

A. What is the dependent variable? [3 points]

B. Identify the sample. [3 points]

C. Have assumptions been met to conduct a single mean z test? Explain how you checked each assumption. [4 points]

D. Is this a one- or two-tailed test? Explain why.

Question

a The following six sales figures (X) were randomly sampled
$28, $34, $40, $44, $52, $54, with ∑X =$252 and ∑X2 = $211,096

i Determine the median and mean. What do these suggest about the distribution of the sales data?

ii What is the standard deviation of the sales data?

iii If a frequency distribution for the sales was constructed, what would be the mid-point and frequency and relative frequency for class “Sales $30 to under $40”?

iv Estimate the 1st quartile for the sales data.

b

You have obtained a data set for 2015, that contains all the work place accidents that occurred at a state government department. The data includes: the gender of worker involved, their education level (high school only, college, university), the cause of the accident (stairs, staplers, other), the cost to the department in dollars, the day of the week, and number of stories in the building in which the accident occurred.

i Identify which variables are categorical and state whether they are nominal or ordinal.

ii Identify which variables are numerical and state whether they are discrete or continuous.

iii If you wished to use the data to predict the average cost to the department per accident for all state government departments in 2015, can the data be used for such a purpose? Why or why not? If so, how? If not, what additional data, or variables, would allow this?

iv If you wished to use the data to predict the chance of an accident occurring for Mondays in 2015 at the state government department, can the data be used for such a purpose? Why or why not? If so, how? If not, what additional data or variables, would allow this?

P7-68B A traveling production of Grease performs each year. The average show sells 1,400 tickets at $50 per ticket. There are 100 shows a year. The show has a cast of 40, each earning an average of $340 per show. The cast is paid only after each show. The other variable expense is program printing expenses of $8 per guest. Annual fixed expenses total $1,582,000. Requirements 1. Compute revenue and variable expenses for each show. 2. Compute the number of shows needed to annually to break even. 3. Compute the number of shows needed to annually to earn a profit of $4,836,400. Is this goal realistic? Give your reason. 4. Prepare Grease’s contribution margin income statement for 100 shows each year. Report only two categories of expenses: variable and fixed.
