50 POINTS FOR AN EXPLANATION & ANSWER FOR #2!!
Sherelle and Venita find two bags of coins in their grandmother’s attic. Each girl selects a bag, takes a random sample of 20 coins from that bag, and lists the dates of those coins as the number of years since 1900. Here are the results.
Sherelle: 72, 56, 81, 84, 75, 26, 39, 62, 65, 66, 85, 71, 74, 68, 73, 66, 83, 60, 58, 72
Venita: 45, 65, 73, 57, 79, 66, 69, 75, 51, 44, 53, 69, 58, 77, 51, 55, 53, 78, 70, 62
1. Find the five-number summary of each data set. Then construct box-and-whisker plots of the data sets. Draw both plots above the same number line. Label the plots with the girls’ names.
Sherelle:
Median - 69.5
Lower quartile - 61
upper quartile - 74.5
lowest value - 26
highest value - 85
Venita:
Median - 63.5
Lower quartile - 53
upper quartile - 71.5
lowest value - 44
highest value - 79
Need help solving the questions below:
(a) Contrast the shapes of the data sets displayed in the box-and-whisker plots in Question 1. Explain what the difference in the shapes means in context of the situation.
(b) Compare the spread of the data sets. Discuss both the overall spread and the spread within the boxes.
(c) Use an appropriate measure of central tendency to compare the center of the data sets. Explain what the difference in those measures means in context of the situation.
