In a study of pulse rates of men, a simple random sample of 140 men results in a standard deviation of 11.6 beats per minute. The normal range of pulse rates of adults is typically given as 60 b 100 beals per minute. It the range rule of thumb is applied to that normal range, the result is a standard deviation of 10 beats per minute. Use the sample results with a 0.10 significance lovel to test the clam that puiso ratis of men have a standard deviation equal to 10 beats per minute; see the accompanying StatCrunch display for this test. What do the results indicate about the effectiveness of using the range rile of thunt initi the "normal range" from 60 to 100 beats per minute for estimating o in this case?

Does it take a different amount of time for seeds to germinate if they are near rock music that is continuously playing compared to being near classical music? The 48 seeds that were exposed to rock music took an average of 28 days to germinate. The standard deviation was 13 days. The 47 seeds that were exposed to classical music took an average of 32 days to germinate. The standard deviation for these seeds was 10 days. What can be concluded at the a - 0.01 level of significance? a. For this study, we should use Select an answer b.

The mean score on a driving exam for a group of drivers education students is 72 points with a standard deviation of 6 points. apply Chebyshev theorem  to the data using K=2. Interpret the results. Simplify answer.

One of the measurements used to determine the health of a person's lungs is the amount of air a person can exhale under force in one second. This is called forced expiratory volume in one second, and is abbreviated FEV,. Assume the mean FEV, for 10-year-old boys is 2.1 liters that the population standard deviation is o =0.2. A random sample of 53 10-year-old boys live in a community with high levels of ozone pollution are found to have a sample mean FEV, of 2.09 liters. Can you conclude that the mean FEV, in the high-pollution community differs from 2.1 liters? (A) Yes (B) No
