Chapter 2: Q 6. (page 104)

Blood pressure Larry came home very excited after a visit to his doctor. He announced proudly to his wife, “My doctor says my blood pressure is at the 90th percentile among men like me. That means I’m better off than about 90% of similar men.” How should his wife, who is a statistician, respond to Larry’s statement?

Short Answer

Expert verified

Not correct.

Step by step solution

01

Given information

"My doctor says my blood pressure is in the 90th percentile among men like me," he boasted to his wife. That indicates I'm in a better position than roughly 90% of similar males.

02

Concept

The percentile of an individual is the percentage of the distribution that is less than the data value of the individual.

03

Explanation

This assertion is incorrect because her blood pressure is higher than 90% of the population of men her age, as defined by the 90th percentile, and hence her blood pressure is high.

Potato chips Refer to Exercise 47 About what percent of 9-ounce bags of

this brand of potato chips weigh less than the advertised 9 ounces? Is this likely to pose a problem for the company that produces these chips?

Quick, click! An Internet reaction time test asks subjects to click their mouse button as soon as a light flashes on the screen. The light is programmed to go on at a randomly selected time after the subject clicks “Start.” The density curve models the amount of time the subject has to wait for the light to flash.

a. What height must the density curve have? Justify your answer.

b. About what percent of the time will the light flash more than 3.75 seconds after the subject clicks “Start”?

c. Calculate and interpret the 38th percentile of this distribution.

Runners’ heart rates The following figure is a Normal probability plot of the heart rates of 200male runners after 6 minutes of exercise on a treadmill.14 Use the graph to determine if this distribution of heart rates is approximately Normal.

I think I can! Refer to Exercise 55. The locomotive’s manufacturer is considering two changes that could reduce the percent of times that the train arrives late. One option is to increase the mean adhesion of the locomotive. The other possibility is to decrease the variability in adhesion from trip to trip, that is, to reduce the standard deviation.

(a) If the standard deviation remains at σ=0.04, to what value must the manufacturer change the mean adhesion of the locomotive to reduce its proportion of late arrivals to less than 2%of days? Show your work.

(b) If the mean adhesion stays atμ=0.37, how much must the standard deviation be decreased to ensure that the train will arrive late less than 2%of the time? Show your worK

(c) Which of the two options (a) and (b) do you think is preferable?. justify your answer. (Be sure to consider the effect of these changes on the percent of days that the train arrives early to the switch point)
