In 1980 and again in 2010, a Gallup poll asked a random sample of 1000 US citizens people "Are you in favor of the death penalty
Digiron [165]

Answer:

H0: p(1980) = p(2010) ; H1 : P(1980) > P(2010)

0.02

Step-by-step explanation:

Given that:

Sample size in both 1980 and 2010 = 1000 samples :

Proportion in favor :

P(1980) = 0.66

P(2010) = 0.64

To test the hypothesis :

Null hypothesis :

Proportion in favor are the same in both years

Null hypothesis = H0 = p(1980) = p(2010)

Alternative hypothesis :

Proportion in favor in 1980 is greater than that in 2010

Alternative hypothesis = H1 : P(1980) > P(2010)

The sample statistic :

P(1980) - p(2010)

0.66 - 0.64

= 0.02

A university's freshman class has 6200 students. 4836 of those students are majoring
WINSTONCH [101]

According to the solving 78% of the freshman class are Economics majors.

<h3>What does a percentage mean?</h3>

percentage, a relative figure signifying hundredths of any amount. Since one percent (symbolized as 1%) is equal to one hundredth of something, 100 percent stands for everything, and 200 percent refers to twice the amount specified.

<h3>Why is it called percent?</h3>

The word "percent" comes from the Latin adverb per centum, which means "by the hundred." In the sixteenth century, the Latin expression made its way into English. Later, it was shortened to % with a final period.

<h3>According to the given data:</h3>

It is given that the total number of students in freshman class = 6200

Total number of students majoring in Economics = 4836

Here, we are asked to find the percentage of the freshman class who are majoring in Economics.

Percent of students majoring Economics =  (Number of students majoring/ Economics  Total number of students) x 100

= \frac{4836}{6200} x 100

= 78%

According to the solving 78% of the freshman class are Economics majors.
