Question

the data represents the heights of eruptions by a geyser. height of eruption (in) 65 30 50 90 80 50 40 70 50 68 78 58 55 65 60 60 77 70 41 89. 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? 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

30, 41, 50, 50, 55, 58, 60, 60, 65, 68, 70, 70, 77, 78, 80, 89

Step2: Find the middle - position

There are \(n = 16\) data points. For an even - numbered data set, the middle positions are \(\frac{n}{2}=8\) and \(\frac{n}{2}+ 1=9\) when the data is sorted in ascending order.

Step3: Identify the middle values

The 8th value is 60 and the 9th value is 65.

Answer:

60, 65
