4. A survey of 35 adult Americans found the mean age (in years) thatpeople would like to live is 87.9 years with a standard deviation of 15.5years. The population is known to be normally distributed with variance16.a) Construct a 98% confidence interval for the true mean ageAmericans want to live.b) Suppose a philosophy professor wishes to test the hypothesesHo: u = 84H1: u + 84Use your confidence interval from part a to test the null hypothesis atthe .02 significance level.

A researcher is interested in studying the use of hypnosis to relieve pain. She took a random sample of 16 subjects and measured their sensory ratings. The mean of the sensory ratings was found to be 7.5 and standard deviation to be 2.3. It is known that the sensory ratings are normally distributed. Construct a 99% confidence interval for the mean sensory ratings of the population. a) (5.81, 9.19) b) (6.27, 8.73) c) (6.36, 8.64) d) (6.02, 8.98)
The average American consumes 97 liters of alcohol per year. Does the average college student consume a different amount of alcohol per year? A researcher surveyed 12 randomly selected college students and found that they averaged 79.1 liters of alcohol consumed per year with a standard deviation of 19 liters. What can be concluded at the the a = 0.05 level of significance? a. For this study, we should use Select an answer b. The null and alternative hypotheses would be: Ho: ? Select an answer H₁: ?

The National Assessment of Educational Progress (NAEP) includes a mathematical test for eighth-grade students. Scores on the test range from 0 to 500. Suppose that you give the NAEP test to an SRS of 2500 eighth-graders from a large population in which the scores have mean u = 282 and standard deviation o = 110. The mean x will vary if you take repeated samples. Suppose that we computed a 90% confidence interval for u. Which is true? This 90% confidence interval could have either a smaller or a larger margin of error than the 95% confidence interval. This varies from sample to sample. This 90% confidence interval would have a smaller margin of error than the 95% confidence interval. This 90% confidence interval would have a larger margin of error than the 95% confidence interval. This 90% confidence interval would have the margin of error as the 95% confidence interval.

I have a question: You are interested in estimating the the mean weight of the local adult population of female white-tailed deer (doe). From past data, you estimate that the standard deviation of all adult female white-tailed deer in this region to be 21 pounds. What sample size would you need to in order to estimate the mean weight of all female white-tailed deer, with a 94% confidence level, to within 4 pounds of the actual weight?
