For each problem, select the best response. (a) The scores of adults on an IQ test is approximately Normal with mean 100 and standard deviation 15. Corinne scores 118 on such test. Her z-score is about O A. 0.67 OB. 1.2 O C. 7.87 OD. 18 O E. None of the above. (b) A researcher wishes to determine whether the rate of water flow (in liters per second) over an experimental soil bed can be used to predict the amount of soil washed away (in kilograms). In this study, the explanatory variable is the O A. size of the soil bed. O B. rate of water flow. OC. amount of eroded soil. O D. depth of the soil bed. O E. None of the above. (c) Smokers don't live as long (on the average) as nonsmokers, and heavy smokers don't live as long as light smokers. You regress the age at death of a group of male smokers on the number of packs per day they smoked. The slope of your regression line A. will be greater than zero. OB. will be less than zero.

Just need #4 In 1905 R Pearl published the article “Biometrical Studies on Man. I. Variation and Correlation in Brain Weight”. According to the study, brain weights of Swedish men are normally distributed with a mean of 1.4 kg and a standard deviation of 0.11 kg. Determine the sampling distribution of the sample mean for samples of size 3. Repeat part (a) for samples of size 12. That is, for parts (a) and (b) discuss the distribution, mean and standard deviation of the sample means for the different sample sizes. Use Excel to construct graphs similar to those shown in Fig 7.4 on page 321 in the textbook. Hand in your excel output and show the data you used to construct the plots, as well as the plots Do you need to assume that brain weights of Swedish men are normally distributed to answer parts (a) and (b)? Explain your answer
In this problem, assume that the distribution of differences is approximately normal. Note: For degrees of freedom d.f. not in the Student's t table, use the closest d.f. that is smaller. In some situations, this choice of d.f. may increase the P-value by a small amount and therefore produce a slightly more "conservative" answer. i need help with (c), sketching the distribution, (d) and (e)
#10. A psychologist is studying the self image of smokers, which she measures by the self image (SI) score from a personality inventory. She would like to estimate the mean SI score, U ( mean population), for the population of all smokers. She plans to take a random sample of SI scores for smokers an estimate U (population mean) via the sample. Assuming that the standard deviation of SI scores for the population of all smokers is 82, what is the minimum sample size needed for the psychologist to be 99% confident that her estimate is within 12 of U (population mean)? Carry your intermediate computations to at least three decimal places write your answer as a whole number, and make sure it is the minimum whole number that satisfies the requirements .
