Given:
Area of rectangle = sq. feet.
Width of the mirror = feet.
To find:
Whether it will fit on the wall whose length is 5 foot.
Solution:
We know that, area of a rectangle is
Substituting the given values, we get
So, length of mirror is 4.75 feet which is less than 5 feet.
Therefore, the mirror will fit on the wall.
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%
