Concept explainers
Age of Marriage A student did a survey on the age of marriage for married male and female students.
a. Is the format of the data set stacked or unstacked?
b. If you answered “stacked” then unstack the data into two columns. If you answered “unstacked” then stack the data into one column; choose an appropriate name for the stacked variable and use coding.
c. There are two variables here: Gender and Age. Which of them is numerical, and which is categorical?

- In a bag, a child has 325 coins worth $19.50. There were three types of coins: pennies, nickels, and dimes. If the bag contained the same number of nickels as dimes, how many of each type of coin was in the bag?arrow_forwardIf a man has 4 sweaters and 5 pairs of slacks, how many different outfit can he wear?arrow_forwardApproaching midseason, the teams in a basketball league had won the following numbers of games.

- Researchers conducted a study on brain size as measured by pixels in a magnetic resonance imagery (MRI) scan. The numbers are in hundreds of thousands of pixels. The data table provides the sizes of the brains and the gender. Complete parts a through c. Click the icon to view the data table of brain size and gender. a. Is the format of the data set stacked or unstacked? The format of the data is stacked. b. Explain the coding. What do 1 and 0 represent? The data value 1 represents and the data value 0 represents c. If you answered "stacked" in part a, then unstack the data into two columns labeled Male and Female. If you answered "unstacked," then stack the data into one column with an appropriate name for the stacked variable. O A. В. С.

The histograms describe the high temperatures in a certain city on each day of one month. The histogram on the left uses class widths of 3°F and the histogram on the right uses class widths of 6°F. Assume that temperature is measured and recorded as whole number values so that the first class would be 64°F-66°F when using a class width of 3°F. Complete parts (a) through (c) below. Daily High Temp. 64 70 76 82 88 94 Degrees Farenheit 64 70 76 82 88 94 Degrees Fareniheit a. During this month, there tends to be two types of weather. The city experiences either cool, foggy days or hot, sunny days. Which of the two histograms better reflects this? O A. The histogram with class widths of 6°F, because the histogram has larger class widths. O B. The histogram with class widths of 6°F, because there are no gaps in the histogram. OC. The histogram with class widths of 3°F, because the two distinct groups of data are separated by a gap in the histogram. O D.
