The number of absences during the fall semester was recorded for each student in a large elementary school. The distribution of absences is displayed in the following cumulative relative frequency graph.

If the distribution of absences was displayed in a histogram, what would be the best description of the histogram鈥檚 shape?

a. Symmetric

b. Uniform

c. Skewed left

d. Skewed right

e. Cannot be determined

Short Answer

Expert verified

The correct option is (d) Skewed right.

Step by step solution

01

Given information

02

Concept

We can investigate the location in a distribution using a cumulative relative frequency graph. You can estimate the percentile for an individual value using the completed graph, and vice versa.

03

Explanation

The cumulative relative frequency graph shows that

Keep in mind that

The slope between 0 and 4 is substantially steeper than the curve between 6 and 14

Then

Because most of the data values are between 0 and 4 (where the histogram's highest bar appears) and relatively few values lie between 6 and 14, the histogram's distribution should be skewed to the right, resulting in low bars tailing to the right side of the highest bars.

Because there are more data values between 0 and 4 than between 6 and 14, we can conclude that skewed right is the best description of the histogram's form. Therefore, the correct answer will be an option (d).

Mean and median The figure displays two density curves that model

different distributions of quantitative data. Identify the location of the mean and median by letter for each graph. Justify your answers.

At some fast-food restaurants, customers who want a lid for their drinks get them from a large stack near the 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 snugly 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 3.95 and 4.05 inches. The restaurant鈥檚 lid supplier claims that the diameter of its large lids follows a Normal distribution with a mean of 3.98 inches and a standard deviation of 0.02 inches. Assume that the supplier鈥檚 claim is true.

Put a lid on it!

a. What percent of large lids are too small to fit?

b. What percent of large lids are too big to fit?

c. Compare your answers to parts (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?

Wear your helmet! Many athletes (and their parents) worry about the risk of concussions when playing sports. A football coach plans to obtain specially made helmets for his players that are designed to reduce the chance of getting a concussion. Here are the measurements of head circumference (in inches) for the players on the team:

a. Antawn, the team鈥檚 starting quarterback, has a head circumference of 22.4 inches. What is Antawn鈥檚 percentile?

b. Find the head circumference of the player at the 90th percentile of the distribution.

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.

Put a lid on it! Refer to Exercise 56. The supplier is considering two changes to reduce the percent of its large-cup lids that are too small to less than 1%. One strategy is to adjust the mean diameter of its lids. Another option is to alter the production process, thereby decreasing the standard deviation of the lid diameters.

(a) If the standard deviation remains at =0.02inches, at what value should the supplier set the mean diameter of its large-cup lids to ensure that less than 1%are too small to fit? Show your method.

(b) If the mean diameter stays at =3.98inches, what value of the standard deviation will result in less than 1%of lids that are too small to fit? Show your method.

(c) Which of the two options in (a) and (b) do you think is preferable? Justify your answer. (Be sure to consider the effect of these changes on the percent of lids that are too large to fit.)
