Question

Review the table and answer the following questions. (5 points)

What’s the total number of participants in the study? (1)

The total participants is 154.

What percentage of males were in the sample? (1)

77% of the participants were males

In males, how many (number and percent) went to the Minnesota study center?

Name a continuous variable that differed between males and females; provide evidence with estimates.

Name a nominal variable that differed between males and females; provide evidence with estimates.

Given that the total number of participants are 154.

77% of the participants are males.

It means that 100% - 77% = 23% of the participants are females.

a) In males, how many (number and percent) went to the Minnesota study center?

Number of males went to the Minnesota study center is,

77% * 154

= (77 / 100) * 154

= 118.58 which approximately equal to 119.

b) Name a continuous variable that differed between males and females; provide evidence with estimates.

If a variable can take on any value between its minimum value and its maximum value, it is called a continuous variable.

The continous variable X is percentage of the male or female.

c) Nominal variables have two or more categories without having any kind of natural order.

Here gender is a nominal variable that differed between males and females.
