Two measures of center are marked on the density curve shown. Which of the following is correct?

a. The median is at the yellow line and the mean is at the red line.

b. The median is at the red line and the mean is at the yellow line.

c. The mode is at the red line and the median is at the yellow line.

d. The mode is at the yellow line and the median is at the red line.

e. The mode is at the red line and the mean is at the yellow line.

Short Answer

Expert verified

The correct option is (b).

Step by step solution

01

Given information

As per given density,

The left -tailed can be defined as the given below:

02

Explanation

As a result, the graph with the provided density resembles the graph above. As a result, the curve is tilted to the right.

As a result, the median is a red line and the mean is at the yellow line.

Put a lid on it! At some fast-food restaurants, customers who want a lid for their drinks get them from a large stack left near straws, napkins, and condiments. The lids are made with a small amount of flexibility so they can be stretched across the mouth of the cup and then snuggly secured. When lids are too small or too large, customers can get very frustrated, especially if they end up spilling their drinks. At one particular restaurant, large drink cups require lids with a 鈥渄iameter鈥� of between 3.95and 4.05inches. The restaurant鈥檚 lid supplier claims that the mean diameter of their large lids is 3.98inches with a standard deviation of 0.02inches. Assume that the supplier鈥檚 claim is true.

(a) What percent of large lids are too small to fit? Show your method.

(b) What percent of large lids are too big to fit? Show your method.

(c) Compare your answers to (a) and (b). Does it make sense for the lid manufacturer to try to make one of these values larger than the other? Why or why not?

Deciles The deciles of any distribution are the points that mark off the lowest 10%and the highest 10%. The deciles of a density curve are therefore the points with area 0.1and 0.9to their left under the curve.

(a) What are the deciles of the standard Normal distribution?

(b) The heights of young women are approximately Normal with mean 64.5inches and standard deviation 2.5inches. What are the deciles of this distribution? Show your work

a. Find and interpret the z-score for North Carolina, with a median household income of $41,553

b. New Jersey had a standardized score of 1.82Find New Jersey鈥檚 median household income for that year.

Shoes Refer to Exercise 1. Jackson, who reported owning 22 pairs of shoes, has a standardized score of z=1.10.

a. Interpret this z-score.

b. The standard deviation of the distribution of the number of pairs of shoes owned in this sample of 20 boys is 9.42. Use this information along with Jackson鈥檚 z-score to find the mean of the distribution.
