The table shows the number of hours that a group of students spent studying for the SAT during their first week of preparation. The students each add 4 hours to their study times in the second week. What are the mean, median, mode, and range of times for the second week?
mean = 14 median = 19 mode = 18.3 range = 9
mean = 18.3 median = 19 mode = 14 range = 9
mean = 19 median = 18.3 mode = 14 range = 0.7
mean =
18.3
median =
19
mode =
14
range =
0.7
The correct answer is:
mean = 18.3
median = 19
mode = 14
range = 9
