91Ó°ÊÓ

The figure shown is the density curve of distribution. Seven values are marked on the density curve. Which of the following statements is true?

a. The mean of the distribution is E.

b. The area between B and F is 0.50.

c. The median of the distribution is C.

d. The 3rd quartile of the distribution is D.

e. The area under the curve between A and G is 1.

Short Answer

Expert verified

The correct option is (e) The area under the curve between A and G is 1

Step by step solution

01

Given information

02

Explanation

It's true because the area beneath the density curve is always one, and the region between Aand G is linked to the entire area beneath the density curve.

Is Michigan Normal? We collected data on the tuition charged by colleges and

universities in Michigan. Here are some numerical summaries for the data:

Based on the relationship between the mean, standard deviation, minimum, and maximum, is it reasonable to believe that the distribution of Michigan tuitions is approximately Normal? Explain your answer.

The army reports that the distribution of head circumference among male soldiers is approximately Normal with mean of 22.8inches and standard deviation 1.1inches.

(a) A male soldier whose head circumference is 23.9-inches would be at what percentile? Show your method clearly.

(b) The army’s helmet supplier regularly stocks helmets that fit male soldiers with head circumferences between 20and 26inches. Anyone with a head circumference outside that interval requires a customized helmet order. What percent of male soldiers require custom helmets? Show your work, including a well-labeled sketch of a Normal curve.

(c) Find the interquartile range for the distribution of head circumference among male soldiers. Show your method clearly.

Household incomes The cumulative relative frequency graph describes the distribution of median household incomes in the 50 states in a recent year.

a. The median household income in North Dakota that year was $55,766Is North Dakota an unusually wealthy state?

b. Estimate and interpret the 90th percentile of the distribution.

Cool pool? Coach Ferguson uses a thermometer to measure the temperature

(in degrees Fahrenheit) at 20different locations in the school swimming pool. An analysis of the data yields a mean of 77°Fand a standard deviation of 3°F(Recall that°C=59°F−1609

a. Find the mean temperature reading in degrees Celsius.

b. Calculate the standard deviation of the temperature readings in degrees Celsius.

Long jump A member of a track team was practicing the long jump and

recorded the distances (in centimeters) shown in the dot plot. Some numerical summaries of the data are also provided.

After chatting with a teammate, the jumper realized that he measured his jumps from the back of the board instead of the front. Thus, he had to subtract 20 centimeters from each of his jumps to get the correct measurement for each jump.

a. What shape would the distribution of corrected long jump distance have?

b. Find the mean and median of the distribution of corrected long-jump distance.

c. Find the standard deviation and interquartile range (IQR) of the distribution of corrected long-jump distance.
