What percent of students in the sample were male?
Round your answer to the nearest percent.

Answer 1

Answer:

The percent of students in the sample who were male is 48%.

Step-by-step explanation:

The complete question is:

Researchers once surveyed 100 students on which superpower they would most like to have. The following two-way table displays data for the sample of students who responded to the survey.

Superpower    Male    Female    TOTAL

Fly                      26           12           38

Invisibility           12           32           44

Other                  10            8            18

TOTAL               48           52          100

What percent of students in the sample were male?

Solution:

The probability of an event E is the ratio of the number of favorable outcomes to the total number of outcomes.

$P(E)=\frac{n(E)}{N}$

The number of males in the sample is, n (M) = 48.

Total number of students, N = 100.

Compute the probability of selecting a male student as follows:

$P(M)=\frac{n(M)}{N}$

          $=\frac{48}{100}\\\\=0.48$

Then the percent of students in the sample who were male is:

$\text{Percent of Males}=P(M)\times 100\%$

                          $=0.48\times 100\%\\\\=48\%$

Thus, the percent of students in the sample who were male is 48%.

Answer 2
