Question

The given data represents the results of a study on infant mortality rates (number of infant deaths per 1000 live births) by country. Full data set 85 133 93 91 114 94 93 72 139 94 98 121 72 105 Use the data table to answer the following questions. a. Find the first quartile (Q1) and the third quartile (Q3). b. Find the interquartile range (IQR). Interpret it. a. The first quartle, 01, is Type an integer or decimal rounded to the nearest tenth as needed.) The third quartile, Q3, is Type an integer or decimal rounded to the nearest tenth as needed.) b. The interquartile range, IQR, is (Type an integer or decimal rounded to the nearest tenth as needed.) What information is given by the interquartile range? A. The middle 50% of values stretch over a range of this value B. Approximately 50% of the data lie below this value.

C. Approximately​ 50% of the data lie above this value.

D. Approximately​ 50% of the data lie within 1 standard deviation of this value.

Answer 1

The Sorted Data Set: 72, 72, 85, 91, 93, 93, 94, 94, 98, 105, 114, 121, 133, 139

The five point summary would be:

Minimum =72

a) Q1= 91

Q2=94

Q3=114

b) Inter quartile range is=IQR=Q3-Q1

=114-91

=23.

The IQR tells that A. The middle 50 % of the values stretch over a range of the value.
