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 <em>E</em> 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, <em>n</em> (M) = 48.

Total number of students, <em>N</em> = 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%.

A poll was taken this year asking college students if they considered themselves overweight. A similar poll was taken 5 years ag
Katyanochek1 [597]

Answer:

At 5% significance level, it is statistically evident that    there is nodifference in the proportion of college students who consider themselves overweight between the two poll                                  

Step-by-step explanation:

Given that a poll was taken this year asking college students if they considered themselves overweight. A similar poll was taken 5 years ago.

Let five years ago be group I X and as of now be group II Y

H_0: p_x =p_y\\H_a: p_x \neq p_y

(Two tailed test at 5% level of significance)

                Group I            Group II              combined p

n                  270                 300                         570

favor            120                  140                          260

p                   0.4444            0.4667                   0.4561

Std error   for differene = \sqrt{\frac{0.4561(1-0.4561)}{570} } \\=0.0209

p difference = -0.0223    

Z statistic = p diff/std error =       -1.066

p value =0.2864

Since p value >0.05, we accept null hypothesis.

        At 5% significance level, it is statistically evident that    there is nodifference in the proportion of college students who consider themselves overweight between the two poll

write an equation in slope-intercept form of the line that passes through the points (1,2) and (-2,-1)
Marizza181 [45]

Answer:

y=3/4x+5/4

Step-by-step explanation:

equation to use: y1-y2/x2-x1 so you get -3/-4 so your slope is 3/4 and you plug that into one of your point equations im going to use the first one so 2=3/4(1) +b so you are going to get 5/4 for b so your equation is y=3/4x + 5/4

Let me know if this helped!
