Varatta Enterprises sells industrial plumbing valves. The following table lists the annual sales amounts for a portion of the salespeople in the organization for the most recent fiscal year. a. Compute the mean (in $1000), variance (in $10002), and standard deviation (in $1000) for these annual sales values. Round your answers to the nearest whole number. b. In the previous fiscal year, the average annual sales amount was 290 thousand with a standard deviation of 95 thousand. Discuss any differences you observe between the annual sales amount in the most recent and previous fiscal years. Which of the following is correct? (i) The difference in the mean annual sales amount is very small and is most likely due to random change in demand for these products. (ii) The sample mean annual sales amount and standard deviation for the previous fiscal year were significantly higher. (iii) The sample mean annual sales amount and standard deviation for the previous fiscal year were significantly…

O Macmillan Learning The domestic cat, Felis catus, is a domesticated furry creature often kept as a pet in many countries. Suppose a volunteer at a local animal shelter wanted to find out a little more about the cats in her care. The volunteer carefully measured the height for the 10 fully grown adult cats at her shelter. The height measurements were taken from the base of the foreleg to the shoulder. The table shows the results of the measurements. Calculate the mean, variance, and standard deviations for cat height for the sample of shelter cats.
