Answer:

(B) set B

Step-by-step explanation:

The greatest spread is the range of the given data set.

(A) The given data set is:

84,91,87,77,94,89,74

Arranging the given data in ascending order, we have

77, 77, 84, 87, 89, 91, 94

The range is given as:

$R=94-74=20$

Thus, the spread of the given data is 20.

(B) The given data set is:

89,73,84,91,87,77,94

Arranging the given data in ascending order, we have

73, 77, 84, 87, 89, 91, 94

The range is given as:

$R=94-73=21$

Thus, the spread of the given data is 21.

73,84,89,88,77,91,87,90

Arranging the given data in ascending order, we have

73, 77, 84, 87, 88, 89, 90, 91

The range is given as:

$R=91-73=18$

Thus, the spread of the given data is 18.

(D) The given data set is:

84,89,88,82,91,87,99

Arranging the given data in ascending order, we have

82, 84, 87, 88, 89, 91, 99

The range is given as:

$R=99-82=17$

Thus, the spread of the given data is 17.

Therefore, set B has the greatest spread that is 21.

A group of pennies made in 2018 are weighed. The mean is approximately 2.5 grams

Hatshy [7]

Answer:

* The mean (a measure of central tendency) weight value is the average of the weights of all pennies in the study.

* The standard deviation (a measure of variability or dispersion) describes the lowest and highest any individual penny weight can be. Subtracting 0.02g from the mean, you get the lowest penny weight in the group.

Step-by-step explanation:

Recall that a penny is a money unit. It is created/produced, just like any other commodity. As a matter of fact, almost all types of money or currency are manufactured; with different materials ranging from paper to solid metals.

A group of pennies made in a certain year are weighed. The variable of interest here is weight of a penny.

The mean weight of all selected pennies is approximately 2.5grams.

The standard deviation of this mean value is 0.02grams.

In this context,

* The mean (a measure of central tendency) weight value is the average of the weights of all pennies in the study.

Likewise, adding 0.02g to the mean, you get the highest penny weight in the group.

Hence, the weight of each penny in this study, falls within

[2.48grams - 2.52grams]
