A set of n = 25 pairs of scores (x and y values) has a pearson correlation of r = 0.80. how much of the variance for the y score
1 answer:
0.64 or 64% of the variance for the y scores is predicted by its relationship with x.
<h3>What is coefficient of determination?</h3>The percentage of the variation in the dependent variable that can be predicted from the independent variable is known as the coefficient of determination, abbreviated R2 or r2, in statistics.
<h3>How to find the variance for the y scores?</h3>given that
A set of n = 25 pairs of scores (x and y values) has a pearson correlation of r = 0.80.
now we have to find the variance for the y scores.
here, r=0.80 then
which means 0.64 or 64% of the variance for the y scores is predicted by its relationship with x.

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%
