Find the regression equation, letting the first variable be the predictor (x) variable. Using the listed lemon/crash data, where lemon imports are in metric tons and the fatality rates are per 100,000 people, find the
best predicted crash fatality rate for a year in which there are 475 metric tons of lemon imports. Is the prediction worthwhile? Use a significance level of 0.05.

(Round the y-intercept to three decimal places as needed. Round the slope to four decimal places as needed.)
The best predicted crash fatality rate for a year in which there are 475 metric tons of lemon imports is fatalities per 100,000 population.
(Round to one decimal place as needed.)
Is the prediction worthwhile?
OA. Since there appears to be an outlier, the prediction is not appropriate.
OB. Since all of the requirements for finding the equation of the regression line are met, the…
A study of seat belt users and nonusers yielded the randomly selected sample data summarized in the accompanying table. Use a 0.05 significance level to test the claim that the amount of smoking is
independent of seat belt use. A plausible theory is that people who smoke are less concerned about their health and safety and are therefore less inclined to wear seat belts. Is this theory supported by the
sample data?

Assume that the amounts of weight that male college students gain during their freshman year are normally distributed with a mean of μ = 1.3 kg and a standard deviation of o=5.5 kg. Complete parts (a)
through (c) below.
a. If 1 male college student is randomly selected, find the probability that he gains between 0 kg and 3 kg during freshman year.
The probability is
(Round to four decimal places as needed.)
b. If 9 male college students are randomly selected, find the probability that their mean weight gain during freshman year is between 0 kg and 3 kg.
The probability is
(Round to four decimal places as needed.)
c. Why can the normal distribution be used in part (b), even though the sample size does not exceed 30?
OA. Since the distribution is of sample means, not individuals, the distribution is a normal distribution for any sample size.
OB. Since the weight gain exceeds 30, the distribution of sample means is a normal distribution for any sample size.
OC. Since the original…
