Second load of wash In Exercise 4, we saw a 98% confi-dence interval of (-40, -22) minutes for mTop - mFront , the difference in time it takes top-loading and front-loading washers to do a load of clothes. Explain why you think each of the following statements is true or false:a) 98% of top loaders are 22 to 40 minutes faster thanfront loaders.b) If I choose the laundromat’s top loader, there’s a 98%chance that my clothes will be done faster than if I hadchosen the front loader.c) If I tried more samples of both kinds of washingmachines, in about 98% of these samples I’d expectthe top loaders to be an average of 22 to 40 minutesfaster.d) If I tried more samples, I’d expect about 98% of the resulting confidence intervals to include the true dif-ference in mean cycle time for the two types of wash-ing machines. e) I’m 98% confident that top loaders wash clothes anaverage of 22 to 40 minutes faster than front-loaders.

This question asks you to extend the medical-test example from class. Suppose there is a medical condition that afflicts 20% of the population. There is a test for this condition, and the reliability of this test can be characterized as follows: false-positive rate = 10% for those who do not have the condition, 10% will test positive. false-negative rate 5% for those who have the condition, 5% will test neg ative. (a) If you receive a positive test result, what is the likelihood that you have the condition? If you receive a negative test result, what is the likelihood that you do not have the condition? (b) Repeat part (a), except now assume that the false-positive rate is 5% and the false-negative rate is 10%.
The advantage of power in an experiment is that, the probability of a Type I error is reduced as power increases, alpha increases as power increases, N increases O you are more likely to detect the real effects of the independent variable, if any exist

A researcher was investigating variables that might be associated with the academic performance of high school students. He examined data from 1990 for each of the 53 cities randomly selected in the US. The dataincluded the average Math SAS score of all high school seniors in the city that took the exam (labeled as the variable SAT-M), the average number of dollars per pupil spent on education by the city (labeled as thevariable $Per Pupil), and the percentage of high school seniors in the city that took the exam (labeled as the variable %Taking). Find the 95% confidence interval for B1, the coefficient of the variable $Per Pupil and find the proportion of the variation in the variable SAT-M is explained by the explanatory variables $Per Pupil and %Taking?

One consumer wants to know if the average number of chips is less than 45 in a bag of Red Bird potato chips. A random sample of 100 was selected and the sample statistics werex=41.6 and s = 7.6. (i) What is the standard error of x? (ii) Using one or two sentences, briefly describe the Central Limit Theorem (CLT) for the sample mean. (ii) Does CLT hold for this test? Explain your reasoning. (iv) State the hypotheses for the test. (v) Give a 90% CI (3 d.p.) for the average amount of chips in each bag (The margin of error is 1.262). (vi) Interpret your Cl in part (iv) in context. (vii) Make a decision and conclusion based on your Cl in part (v).
