Listed below are the durations​ (in hours) of a simple random sample of all flights of a space shuttle. Find the​ (a) mean,​ (b)
-Dominant- [34]

Answer:

Mean = 212.93

Median = 231

Mode = 231

Mid range = 192.5

(B) ​Yes, the time of 0 hours is very unusual. It could represent a flight that was aborted.

Step-by-step explanation:

We are given the following data set:

8, 92, 231, 189, 169, 267, 196, 381, 257, 231, 385, 330, 219, 239, 0

Formula:

a)

Mean = \displaystyle\frac{\text{Sum of all observations}}{\text{Total number of observation}}

Mean =\displaystyle\frac{3194}{15} = 212.93

b)

Median:\\\text{If n is odd, then}\\\\Median = \displaystyle\frac{n+1}{2}th ~term \\\\\text{If n is even, then}\\\\Median = \displaystyle\frac{\frac{n}{2}th~term + (\frac{n}{2}+1)th~term}{2}

Sorted data:

0, 8, 92, 169, 189, 196, 219, 231, 231, 239, 257, 267, 330, 381, 385

\text{Median} = \dfrac{15 + 1}{2}^{th}\text{ term} = 8^{th}\text{ term} = 231

Mode is the most frequent observation in the data.

Mode = 231

It repeated 2 times.

\text{Mid range} = \dfrac{\text{Maximum value + Minimum value}}{2}\\\\= \dfrac{385 + 0}{2} = 192.5

0 is an outlier to the given dataset. Thus,

Option (B) ​Yes, the time of 0 hours is very unusual. It could represent a flight that was aborted.
