Assignment 2If the uric acid values in normal adult males areapproximately normally distributed with a mean andstandard deviation of 5.7 and 1 mg percent, respectively,find the probability that a sample of size 10 will yield amean:Greater than 6.5 C. Between 5 and 6Less than 5The same survey database cited in exercise 4.3.1 (A-5) shows that 32 percent of U.S. adults indicated thatthey have been tested for HIV at some point in theirlife. Consider a simple random sample of 15 adultsselected at that time. Find the probability that thenumber of adults who have been tested for HIV in thesample would be:(a) Three (b) Less than five(c) Between five and nine, inclusive(d) Find the probability that the number of adults whohave not been tested for HIV in the sample would be: Sixor more(e) Find the mean and variance of the number of peopletested for HIV in samples of size 15.

Suppose that the sitting back-to-knee length for a group of adults has a normal distribution with a mean of mu equals 23.5 in. and a standard deviation of sigma equals 1.1 in. These data are often used in the design of different seats, including aircraft seats, train seats, theater seats, and classroom seats. Instead of using 0.05 for identifying significant values, use the criteria that a value x is significantly high if�� P(x or greater)less than or equals 0.01 and a value is significantly low if P(x or less)less than or equals 0.01. Find the back-to-knee lengths separating significant values from those that are not significant. Using these criteria, is a back-to-knee length of 25.6 in. significantly high?

A triathlon consisting of swimming, cycling, and running is one of the more strenuous amateur sporting events. An article reports on a research study involving nine male triathletes. Maximum heart rate (beats/min) was recorded during performance of each of the three events. For swimming, the sample mean and sample standard deviation were 187.0 and 7.2, respectively. Assuming that the heart-rate distribution is (approximately) normal, construct a 98% CI for true mean heart rate of triathletes while swimming. (Round your answers to one decimal place.) USE SALT beats/min You may need to use the appropriate table in the Appendix of Tables to answer this question.

Suppose that the sitting back-to-knee length for a group of adults has a normal distribution with a mean of μ = 23.7 in. and a standard deviation of o=1.1 in. These data are often used in the design of different seats, including aircraft seats, train seats, theater seats, and classroom seats. Instead of using 0.05 for identifying significant values, use the criteria that a value x is significantly high if P(x or greater) ≤ 0.01 and a value is significantly low if P(x or less) ≤0.01. Find the back-to-knee lengths separating significant values from those that are not significant. Using these criteria, is a back-to-knee length of 25.8 in. significantly high? Find the back-to-knee lengths separating significant values from those that are not significant. Back-to-knee lengths greater than in. and less than in. are not significant, and values outside that range are considered significant. (Round to one decimal place as needed.) rect: 0
