A) See picture for the table.
To make the table, multiply 47774 by 1.5% to get total that have diabetes and multiply 5855 by 2.5% to get total unemployed that have it, then using subtraction fill in the other squares of the table.
B)
Hypothesis:
H0: No association between employment and diabetes.
H1: Association between the two
Using a graphing calculator or Excel, run a chi-test.
Chi squared equals 31.844 with 1 degrees of freedom.
The two-tailed P value is less than 0.0001
With this information we can reject the null hypothesis and conclude there is an association between diabetes and employment.
C)
Although there is a statistical significance, there really is no practical significance between an incidence rate of 1.5 or 2.5%
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
= x 100
= 78%
According to the solving 78% of the freshman class are Economics majors.
