A. Yes, the distribution is roughly symmetric and there are no outliers. O B. No, the distribution is roughly symmetric with no outliers. C. No, the boxplot shows there are outliers O D. Yes, the distribution is highly skewed with outliers. If the boxplot suggests a confidence interval can be constructed, calculate and interpret the lower bound and the upper bound of the confidence interval. Select the correct choice below and, if necessary, fill in the answer boxes to complete your choice. Round to the nearest dollar. Use ascending order.) O A. We are 95% confident that the mean cost of repair is between $ and $ O B. There is a 95% probability that the mean cost of repair is between $ and $. O C. The confidence interval should not be constructed. Help Me Solve This View an Example Get More Help - Clear All Check Answer7 through (d). The trade volume of a stock is the number of shares traded on a given day. The data in the first accompanying table, in millions (so that 6.16 represents 6, 160,000 shares traded), represent the volume of a PepsiCo stock traded for a random sample of 38 trading days in 2018. A second random sample of 38 days in 2018 resulted in the data in the second accompanying table. Complete parts (a) Click here to view the data for sample 1. Click here to view the data for sample 2.
