1. The following data represent the exchange rates for Currency A in terms of Currency B for 14 months. Complete parts a through e below.

0.67	0.73	0.93	1.12	1.43	0.95	0.76
0.58	1.51	0.58	0.54	0.85	1.39	0.90

a.) Calculate the mean.

The mean is $_________(Round to three decimal places as needed.)

b.) Calculate the median.

The median is $__________.(Round to the nearest cent as needed.)

c.) Determine the mode. Select the correct choice below and, if necessary, fill in the answer box to complete your choice.

A.The mode(s) is/are $___________.

(Type an integer or a decimal. Use a comma to separate answers as needed)

B. There is no mode for this data set.

d.) Which of the three measurements would best describe the central tendency of this data?

A. The median would be a better indicator of the central tendency of the exchange rate since there appear to be outliers.

B. The mode is the better indicator of the central tendency of the exchange rate since this data is categorical.

C. Both the mean and the median are accurate indicators of the central tendency of the exchange rate since there do not appear to be any outliers.

D. The mean would be a better indicator of the central tendency of the exchange rate since there appear to be outliers.

e.) Describe the shape of the distribution. Choose the correct answer below.

A. The data appear to be right-skewed because the mean is greater than the median.

B. The data appear to be left-skewed because the mean is less than the median.

C. The data appear to be symmetric because the mean is equal to the median.

2. The "high school female athletes" data file has data for 57 high school female athletes on the maximum number of pounds they were able to bench press, which is a measure of strength. For these data x=82.2, Q1=72, median=82, Q3=92. Complete parts (a) and (b).

a. Interpret the quartiles.

One (1)_________ had a maximum bench press less than _________ pounds, and one fourth had a maximum bench press (2)_________ than 92 pounds.

b. Would you guess that the distribution is skewed, or roughly symmetric?

A. There's not enough evidence to decide.

B. Roughly symmetric

C. Skewed

A. Q1

B. mean

C. median

D. standard deviation

E. Q3

Choose the correct box plot below.

A.

65120

A boxplot has a horizontal axis labled from 65 to 120 in increments of 5. A box encloses three vertical line segments at the following values: 84, 87, 103. Horizontal line segments extend outward from both sides of the box to 72 and 114.

B.

65120

A boxplot has a horizontal axis labled from 65 to 120 in increments of 5. A box encloses three vertical line segments at the following values: 80, 91, 107. Horizontal line segments extend outward from both sides of the box to 73 and 113.

C.

65120

A boxplot has a horizontal axis labled from 65 to 120 in increments of 5. A box encloses three vertical line segments at the following values: 80, 91, 107. Horizontal line segments extend outward from both sides of the box to 69 and 117.

D.
