Answer:
H0:p1=p2; Ha:p1≠p2, which is a two-tailed test.
Step-by-step explanation:
We formulate our hypotheses as
H0:p1=p2; Ha:p1≠p2, which is a two-tailed test.
Supposing the probability or proportion of the first survey is equal to the probability or proportion of the second survey. This will be the null hypothesis and the alternative hypotheses would be that these two proportions or probabilities are unequal.
This is a two tailed test.
10,500 mosquitos because 1,000•10hr=10,000 then half of a thousand is 500 so it's that
The number of sod grasses needed is about one and half for the clients lawn
1 1/2 sod grasses
<h3> Area of Rectangle</h3>
Given Data
Area of client's Lawn = Length * Width
= 75*100
= 7500 square feet
Size of large rolls of sod grass
Area of large rolls of sod grass = Length * Width
= 116*42
= 4872 square feet
The number of sod grass needed
= 7500/4872
= 1.53

First, we calculate the area of one paver. This is:
12 x 12 = 144 square feet
Now, the number of pavers required may be determined by dividing the total surface area to be covered by the surface area of one paver, as:
number of pavers = 600 / 144
Number of pavers = 4.2
Because 0.2 pavers can not be obtained, 5 pavers are needed to completely cover 600 square feet.
