Answer 2

3. Find the mean, median, and mode of the data set. Round to the nearest tenth.

15, 13, 9, 9, 7, 1, 11, 10, 13, 1, 13 (1 point)
mean = 9.3, median = 8, mode =13
mean = 8.5, median = 10, mode = 13******
mean = 9.3, median = 10, mode = 13
mean = 8.5, median = 10, mode = 8

4. Find the mean, median, and mode of the data set. Round to the nearest tenth.

Test scores on a math exam:
88, 89, 65, 62, 83, 63, 84, 63, 74, 64, 71, 82, 66, 88, 79, 60, 86, 63, 93, 99, 60, 85 (1 point)mean = 75.8, median = 79.5, mode = 63
mean = 75.8, median = 76.5, mode = 63
mean = 69.5, median = 76.5, mode = 63*******
mean = 69.5, median = 76.5, mode = 79.5

16. A store sells five models of cameras for $190.00, $420.00, $270.00, $300.00, and $420.00. If the sales tax rate is 6%, what are the mean, median, mode, and range of the total cost of the cameras? (1 point)
mean = $318.00
median = $339.20
mode = $445.20
range = $21.20

mean = $339.20*****************
median = $318.00
mode = $445.20
range = $243.80

mean = $339.20
median = $318.00
mode = $445.20
range = $21.20

mean = $445.20
median = $318.00
mode = $339.20
range = $243.80
