To investigate the relationship between yield of potatoes and level of fertilizer application, a researcher divides a field into

eight plots of equal size and applies differing amounts of fertilizer to each. The yield of potatoes in pounds and the amount of fertilizer in pounds are recorded for each plot. The data are as follows:
Fertilizer (pounds), x Yield (pounds), y
1 25
1.5 31
2 27
2.5 28
3 36
3.5 35
4 32
4.5 34
Find the prediction equation for the regression of yield on fertilizer. Round values to four decimal places.
a. ˆy=24.4524+2.3810x
b. ˆy=27.6073+1.3872x
c. ˆy=22.1023+2.9840x
d. ˆy=25.1523+2.1511x

Please anyone help

5.46 to 3 sig figs means the range is {5.455,5.465} and 17.74 means the range {17.735,17.745}.
p=q²/r has a maximum value when q=5.465 and r=17.735 and a minimum value when 5.455 and r=17.745.
So the range of p is 1.6769 to 1.6840. When we have 2 decimal places we get p=1.68 which accommodates the maximum and minimum values of the range. So 2 decimal places is a suitable degree of accuracy, or we could say 3 significant figures.

13. The perimeter P (in yards) of a soccer field is represented by the formula P = 24 + 2w,
rjkz [21]

Answer:

w = \frac{1}{2}(P - 24)

w = 153\ yards

Step-by-step explanation:

Given

P = 24 + 2w

Require

Solving (a):

P = 24 + 2w

Subtract 24 from both sides

P-24 = 24-24 + 2w

P-24 = 2w

Divide both sides by 2

\frac{1}{2}(P - 24) = \frac{2w}{2}

\frac{1}{2}(P - 24) = w

w = \frac{1}{2}(P - 24)

Solving (b):

Substitute 330 for P un the expression in (1)

w = \frac{1}{2}(330 - 24)

Evaluate the bracket

w = \frac{1}{2}(306)

w = 153\ yards
