The following data give the annual salaries (in thousand dollars) of 20 randomly selected health care workers. 50 72 56 38 46 65 37 51 34 62 73 40 68 44 76 61 57 55 65 58 a. Calculate the values of the three quartiles and the interquartile range.

So, the interquartile range is IQR=22.5.

Step-by-step explanation:

Let us write the numbers in ascending order:

34, 37, 38, 40, 44, |  46, 50, 51, 55, 56, |

57, 61, 62, 65, 65, | 68, 68, 72, 73, 76.

We calculate quartile 1:

We calculate quartile 2:

We calculate quartile 3:

We calculate the interquartile range:

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value

0,0
