Question

find the midrange of the data set. 31.2 48.6 54.8 47.6 51.5 35.8 37.3 42.8 (1 point) 45.2 43.0 43.7 44.1

Explanation:

Step1: Find the maximum and minimum values

The given data set is \(31.2, 48.6, 54.8, 47.6, 51.5, 35.8, 37.3, 42.8\).
The maximum value \(M = 54.8\) and the minimum value \(m=31.2\).

Step2: Calculate the mid - range

The formula for mid - range is \(\text{Mid - range}=\frac{M + m}{2}\).
Substitute \(M = 54.8\) and \(m = 31.2\) into the formula: \(\frac{54.8+31.2}{2}=\frac{86}{2}=43.0\)

Answer:

43.0
