Using the following set of data, calculate the lower quartile, the upper quartile, and the interquartile range.20, 22, 25, 28, 29, 30, 32, 33, 34
Be sure to show your work for finding:
The lower quartile
The upper quartile
The interquartile range

The lower quartile is 23.5

The upper quartile is 32.5

The interquartile range is 9

Step-by-step explanation:

The given data set is 20, 22, 25, 28, 29, 30, 32, 33, 34.

The data set is already sorted in ascending order.

The middle number of this data set is called the median.

Therefore the median is 29.

The median divides the data set into two halves.

The lower half is

20, 22, 25, 28

The median of the lower half is the lower quartile.

The upper half is 30, 32, 33, 34

The median of the upper half is the upper quartile.

The interquartile range is given by

option: d is the correct answer.

d) none of the above.

step-by-step explanation:

clearly from the figure attached to the question we could see that there is no shape given. hence without any shape given in the figure and after rotation we can't obtained a square pyramid.

since, to obtain a image we need a proper figure of the pre-image so that it can be transformed.

hence, the correct answer is:

d) none of the above.
