Answer:
40/3
Step-by-step explanation:
w = weight of soil needed
f = number of flower beds
a = constant value
w = a * f
<em>substitute</em>
10 = 6a
<em>simplify</em>
5/3 = a
w = (5/3)f
<em>plug in 8</em>
w = (5/3)(8)
<em>simplify</em>
w = 40/3

Step-by-step explanation:
Information given
n=370 represent the sample selected
estimated proportion of readers owned a laptop
is the value that we want to test
z would represent the statistic
represent the p value

We need to conduct a hypothesis in order to test if the true proportion of readers owned a laptop is different from 0.45, the system of hypothesis are:
Null hypothesis:
Alternative hypothesis:
The statistic is:
(1)
Replacing we got:
Calculating the p value
We have a bilateral test so then the p value would be:
The value of y is -7 because you will add 4 on both sides and adding to negatives is adding and keeping the sign of the larger number.
