Answer 1

To find the mean of the given data, sum up all the values and divide by the number of values. Mean = 23.6.

Step-by-step explanation:

To find the mean of the data, we need to add up all the values and divide by the number of values. Based on Solution 2.27, the calculation for the mean is as follows:

x = [3+ 4+ (8)(2) + 10 + 11 + 12 + 13 + 14 + (15)(2) + (16)(2) + (17)(2) + 18 + 21 + (22)(2) + (24)(2) + 25 + (26)(2) + (27)(2) + (29)(2) +31 +32 + (33)(2) + (34)(2) + 35 +37 + 40 + (44)(2) +47] / 40

= 23.6.
