A supermarket is testing brands of microwave popcorn. For each brand, they recorded the percentage of corn kernels in a package that popped in the recommended cooking time. Let A be the data set of percentages listed below. A = {91, 94, 89, 93, 87, 92, 86, 87, 92, 91} The supermarket then realized they missed a brand. When the new brand was cooked, only 74% of its kernels popped. Let B be the data set of percentages for all 11 packages, including the package where the least kernels popped. Select the statements that are true. The standard deviation of B is greater than the standard deviation of A. The mean of A is the same as the mean of B. Including the percentage for the package where the least kernels popped causes the center of the data to increase. The interquartile range of A is the same as the interquartile range of B. The median of A is the same as the median of B. Including the percentage for the package where the least kernels popped causes the spread of the data to decrease.
