{Exercise 3.29 (Algorithmic)}

The results of a national survey showed that on average, adults sleep 6.9 hours per night. Suppose that the standard deviation is 1 hours.

Round your answers to the nearest whole number.

Use Chebyshev's theorem to calculate the percentage of individuals who sleep between 4.9 and 8.9 hours.
At least %
Use Chebyshev's theorem to calculate the percentage of individuals who sleep between 3.9 and 9.9 hours.
At least %
Assume that the number of hours of sleep follows a bell-shaped distribution. Use the empirical rule to calculate the percentage of individuals who sleep between 4.9 and 8.9 hours per day.

7/ The results of an experiment on the effects of sleep training on sleep quality showed that participants who received eight sessions of sleep enhancement training had longer sleep duration and better sleep quality than participants who did not receive the training. This led the researchers to conclude that an eight-week sleep enhancement training program is effective for improving sleep quality. What advantage of experimental research does this demonstrate? Multiple Choice Question Experimental research helps establish cause and effect relationships....

An article presents results of a survey of adults with diabetes. The average body mass index (BMI) in a sample of 15 men was 30.4, with a standard deviation of 0.6. The average BMI in a sample of 19 women was 31.1 with a standard deviation of 0.2. Assuming BMI is normally distributed, find a 95% confidence bound for the difference in mean BMI between men and women with diabetes. Be sure to interpret the interval in context.

The National Sleep Foundation used a survey to determine whether hours of sleep per night are independent of age (Newsweek, January 19, 2004). A sample of individuals was asked to indicate the number of hours of sleep per night with categorical options: fewer than 6 hours, 6 to 6.9 hours, 7 to 7.9 hours, and 8 hours or more. Later in the survey, the individuals were asked to indicate their age with categorical options: age 39 or younger and age...

Problem 3. Americans average 6.9 hours of sleep on weeknights, according to a report released in 2011 by the National Sleep Foundation. The Dean of Student Affairs at the College of the Canyons wondered if the average amount of sleep on weeknights is less for students at their college. She collected data from a survey of 90 randomly selected students at her college. Respondents averaged 6.4 hours of sleep a night with a standard deviation of 1.35 hours. Here is...

a) The average nightly sleep time for adults is 7.4 hours a night with a standard deviation of 2.3 hours. A researcher suspects that college students’ sleep time may vary from this average. She surveys a sample of 12 college students and obtains the following nightly sleep times for this sample: Participant/Sleep Time (hours) A - 3 B - 4.5 C - 9 D - 7 E - 8 F - 5 G - 6 H - 4 I -...

A national survey of heads of households showed the percentage of those who asked for a raise and the percentage who got one. According to the survey, of the women interviewed, 26% had asked for a raise, and of those women who had asked for a raise, 45% received the raise. Suppose a woman is randomly selected, then: (a) Find P (woman did not ask for a raise). (b) Find P (woman asked for raise and received raise). You are...
