Question

the data represents the heights of eruptions by a geyser. height of eruption (in.) 69 80 50 57 78 36 50 66 65 70 50 40 72 68 44 90 70 54 60 80 use the heights to construct a stemplot. identify the two values that are closest to the middle when the data are sorted in order from lowest to highest. which plot represents a stemplot of the data? a. 3 4 5 6 7 8 9 047 049 006 005 028 00 b. 3 4 5 6 7 8 9 6 04 007 05689 0028 000 c. 3 4 5 6 7 8 9 6 045689 0028 0047 000

Explanation:

Step1: Sort the data

36, 40, 44, 47, 49, 50, 50, 50, 54, 57, 60, 65, 66, 68, 69, 70, 70, 72, 78, 80, 80, 90

Step2: Find the middle - two values (since there are 22 data points)

The middle is between the 11th and 12th ordered values. The 11th value is 60 and the 12th value is 65.

Step3: Check stemplots

For a stemplot, the tens digit is the stem and the units digit is the leaf. Analyze each option to match the data distribution.

Answer:

(No stemplot options are clearly legible in the provided image to determine the correct stemplot. But the two values closest to the middle when sorted are 60 and 65)
