bazaltina [42]

Answer:

a) H0: p > 0.0016

H1: p ≤ 0.0016

Step-by-step explanation:

A null hypothesis states that there is no relation between two variables, it's what the researcher wants to discredit.

On the other hand, the alternative hypothesis is what the researcher tries to prove.

<u>The claim of this entomologists is that fewer than 16 in ten thousand male fireflies are unable to produce light due to a genetic mutation. Therefore, this claim is what he wants to prove and it would be the alternative hypothesis.</u>

H1: p ≤ 0.0016

The null hypothesis would be the opposite of the alternative hypothesis and therefore it would be:

H0: p > 0.0016

The rubber playground mulch is sold in packages that cover 300 square feet each. what expression represents the number of packag
tino4ka555 [31]

The expression represents the number of packages of mulch that will be needed to cover both rounded ends is 600/x

<h3>How to determine the expression represents the number of packages of mulch that will be needed to cover both rounded ends?</h3>

The given parameters are:

Area covered = 300 square feet

Number of ends  = 2

So, the total surface area is:

Total surface area = Area covered * Number of ends  

This gives

Total surface area = 300 * 2

Total surface area = 600 square feet

Let the area covered by each package of mulch be x.

So, the number of mulch is

Number = Area covered/area covered by each

This gives

Number = 600/x

Hence, the expression represents the number of packages of mulch that will be needed to cover both rounded ends is 600/x
