Answer:
The null hypothesis is 
The alternative hypothesis is 
Step-by-step explanation:
From the question we are told that
The number observations is 
The annual salary (in dollars) is y
The mean score on teaching evaluation is x
The the relationship between the y and x is

Where
is the mean of the equation so
The null hypothesis is 
The alternative hypothesis is 
<span>σ</span> is a symbol for summation that means that it is used to add all the vales of the equation in the range
for example taking 0<x<4 and x is an integer
so Ď(x - 2)^2= (1-2)^2+(2-2)^2+(3-2)^2
The options were
a. Square each value
b. Subtract 2 points from each score
C. Sum the squared values
d. Subtract 22 from each X2 value
As we can see above the answer is C. Sum the squared values
We should fuigre it out by first doing 1.7x since we don't know the 2 different widths and lengths.
P= 2*length + 2*width(the distance around)
Question says...
2(1.7x)+2x = 28
3.4x+2x=28
5.4x=28
X= 28m divided by 5.4
x = 5.2m: the width The length is : 8.8m
Consent is 5 coefficient is 3x hope this helps
