Question

find the mean. select the correct choice below and, if necessary, fill in the answer box to complete your choice. (round to one decimal place as needed.) a. the mean is □ b. the mean cannot be calculated because there is an even number of data values. c. the mean cannot be calculated because the data are at the nominal level of measurement. d. the mean cannot be calculated because the sample size is too small.

Explanation:

Step1: Extract data from stem-and-leaf plot

Data: 6,7,13,14,17,20,20,24,27,27,29,33,33,33,34,36,38,38,39,41,43,44,45,46,52 (25 values)

Step2: Calculate mean

Sum=759, Mean=$\frac{759}{25}=30.36\approx30.4$

Step3: Find median (13th value)

Ordered data: 6,7,13,14,17,20,20,24,27,27,29,33,33,33,34,... Median=33

Step4: Determine mode (most frequent)

33 appears 3 times. Mode=33

Answer:

Mean: 30.4, Median: 33, Mode: 33
