Question

the movement of the progress bar may be uneven because questions can be worth more or less (including zero) depending on your answer. santos takes the train into the city five days a week for work. for one work week, he kept track of how many minutes long each train ride was: 48 51 48 48 50 calculate the mean, median, range, and midrange of the train ride times for the week. mean, 49; median, 48; range, 3; midrange, 49.5 mean, 3; median, 49.5; range, 49; midrange, 48 mean, 49.5; median, 49; range, 48; midrange, 3 mean, 48; median, 3; range, 49.5; midrange, 49

Explanation:

Step1: Calculate the Mean

First, sum the data values: \(48 + 51 + 48 + 48 + 50 = 245\). Then divide by the number of data points (5): \(\frac{245}{5}=49\).

Step2: Calculate the Median

Arrange the data in order: \(48, 48, 48, 50, 51\). The middle value (3rd term) is 48.

Step3: Calculate the Range

Subtract the minimum from the maximum: \(51 - 48 = 3\).

Step4: Calculate the Midrange

Find the average of the minimum and maximum: \(\frac{48 + 51}{2}=\frac{99}{2}=49.5\).

Answer:

A. Mean, 49; Median, 48; Range, 3; Midrange, 49.5
