Question

You have a distribution summarizing the number of days in the past two months (60 days) that an individual watched TV. The median number of days = 25, the lower quartile = 21, and upper quartile = 42. Given this information, which of the following statements are true?

(Points : 1)
This distribution is roughly normally distributed.

The threshold value for the upper outlier is 31.5.

This distribution is skewed to the right.

There are no outliers in this distribution.

The lower outlier threshold value is 10.

All good I just guessed oh well

Answer 1

It should have been There are no outliers in this distribution

Answer 2

Given:
Data Set: 60 items
Median: 25
lower quartile or Q1: 21
upper quartile or Q3: 42

IQR = Q3 - Q1 = 42 - 21 = 21

The DISTRIBUTION IS SKEWED TO THE RIGHT.

distance between median and Q1: 25 - 21 = 4
distance between Q3 and median: 42 - 25 = 17

Since the distance between Q3 and median is greater than the distance between the median and Q1, the distribution is skewed to the right.
