Answer:
a. 20.23
b. 14.1
c. 8.3, 9.2, 9.8, 12.1, 13.5, 14.7, 26.5, 34.7, 36.5, 37
d. 22.65
Step-by-step explanation:
Sum = 202.3
Count = 10
Mean = 202.3 / 10
Mean = 20.23
Since there is an even number of data values the median is the mean of the two data values in the middle, calculated as follows;
8.3, 9.2, 9.8, 12.1, 13.5, 14.7, 26.5, 34.7, 36.5, 37
Median = (13.5 + 14.7) / 2
Median = 14.1
Mode is the value or values in the data set that occur most frequently. Since all are occurred once so all the values will be considered as Mode;
Mode = 8.3, 9.2, 9.8, 12.1, 13.5, 14.7, 26.5, 34.7, 36.5, 37
Midrange = (Highest Value + Lowest Value) / 2
Midrange = (37 + 8.3) / 2
Midrange = 22.65
