Homework Answers
From the given information,
a.
Sum of observations (S)=213
Number of observations (n)=7
Hence,
Mean of distribution=S/n=213/7=30.42
Now,
Median is value of 4th observation when data is arranged in increasing order.
Median=22
And
Mode is the frequently observed observation.
Here, 18 is observed for 2 times.
Hence,
Mode=18
b.
Here Mode will be more useful because observation 18 has more chances to occur again and again.
Thank you.

Discrete vs. Continuous Random Variable: You will notice that there is most ikely no mode for the sample data set presented in Table 1. The reason there are not multiple instances of exactly the same value of the random variable is due to the continuous nature of the random variable. Continuous random variables are random variables whose value can take on infinitely many values- the value of which is typically governed by the precision of the device used to measure...
