To find the inverse, interchange the variables and solve for y.
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
(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 =
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
we know that
In a right triangle
Applying the Pythagorean Theorem
where
a and b are the legs of the triangle
c is the hypotenuse of the triangle
Step N
<u>Assume that the third side is a leg</u>
In this case we have
Solve for b
substitute the values
Step N
<u>Assume that the third side is the hypotenuse</u>
In this case we have
substitute the values
Step N
<u>Find the difference of the third sides</u>
therefore
<u>the answer is</u>
22 miles is equal to 1393920 inches
<em><u>Solution:</u></em>
Given that, we have to convert 22 mile to inches
1 Mile (mi) is equal to 63360 inches (in). To convert miles to inches, multiply the mile value by 63360
<em><u>Use the following conversion factor</u></em>
Given is 22 miles
<em><u>Thus, multiply 63360 by 22</u></em>
Thus 22 miles is equal to 1393920 inches
