Question

1. Suppose annual salaries for sales associates from a particular store have a mean of $32,500 and a standard deviation of $2,500. Calculate and interpret the z-score for a sales associate who makes $36000.  Suppose that the distribution of annual salaries for sales associates at this store is bell-shaped. Use the empirical rule to calculate the percentage of sales associates with salaries between $27500,000 and $37,500.

2. In a statistics class 10 scores were randomly selected with the following results were obtained (mean=71.5): 74, 73, 77, 77, 71, 68, 65, 77, 67, 66. Compute the variance and 90th percentile

Please show calculations only and do not use formulas. I need to see the calculations broken down so that I can know how you got to the solution. Thank you.

Explanation / Answer

: z = (27500-32500)/2500 = 2
