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, 3; median, 49.5; range, 49; midrange, 48 mean, 48; median, 3; range, 49.5; midrange, 49 mean, 49; median, 48; range, 3; midrange, 49.5 mean, 49.5; median, 49; range, 48; midrange, 3

Explanation:

Step1: Calculate the mean

The mean $\bar{x}=\frac{48 + 51+48+48+50}{5}=\frac{245}{5}=49$.

Step2: Find the median

Arrange the data in ascending - order: $48,48,48,50,51$. The middle value is the third value, so the median is $48$.

Step3: Calculate the range

The range is the difference between the maximum and minimum values. Range $=51 - 48=3$.

Step4: Calculate the mid - range

The mid - range is $\frac{\text{Maximum}+\text{Minimum}}{2}=\frac{51 + 48}{2}=\frac{99}{2}=49.5$.

Answer:

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