priority questionThe dot plots below show the test scores of sixth- and seventh-grade students: Dot plot for Grade 6 shows 6 dots on score 70, 4 dots on score 80, 6 dots on score 90, and 4 dots on score 100. Dot plot for Grade 7 shows 5 dots on score 50, 7 dots on score 60, 4 dots on score 70, and 4 dots on score 80. Based on visual inspection of the dot plots, which grade, if any, appears to have the higher mean score? Grade 6 Grade 7 Both groups show about the same mean score. No conclusion about mean score can be made from the data.

450 people are randomly selected at grocery stores across the state and surveyed on the amount of money they are spending at the store that day. How does finding the sample variance compare to investigating the sampling distribution of the variance?A.Since the state has at least 450 grocery stores, finding the variance of the sample is the same as investigating the sampling distribution of the variance.B.The sampling distribution of the variance requires repeating this process with the same sample several times. So this does not compare to the sampling distribution of the variance.C. Only 450 people are selected from all the shoppers, so the distribution is not even.D.The sampling distribution of the mean requires multiple samples to be compared. However, in this situation you are looking for the variance, so finding the sample variance is the same as investigating the sampling distribution of the variance.
