Question

the data represents the heights of eruptions by a geyser. height of eruption (in.) 64 38 50 90 80 50 40 70 50 63 73 58 52 68 68 60 79 70 47 88 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. identify the two values that are closest to the middle when the data are sorted in order from lowest to highest. the values closest to the middle are inches and inches (type whole numbers. use ascending order).

Explanation:

Step1: Sort the data

38, 40, 47, 50, 50, 52, 58, 60, 63, 64, 68, 68, 70, 70, 73, 79, 80, 88, 90

Step2: Find the middle - position

There are \(n = 19\) data points. The middle position is \(\frac{n + 1}{2}=\frac{19+1}{2}=10\)th value.
The 9th value is 63 and the 10th value is 64.

Answer:

63, 64
