The makers of Mini-Oats cereal have an automated packaging machine that is set to fill boxes with 24 ounces of cereal. At various times in the packaging process, we select a random sample of 100 boxes to see whether or not the machine is filling the boxes with an average of 24 ounces of cereal. Which of the following is a statement of the null hypothesis?

H' : u = 24

Step-by-step explanation: Let H' represents the null hypothesis and H1 represents the alternative hypothesis.

From the question, the initial claim or assertion is that the machine is set to fill 24 ounces of cereal.

Hence H' : u = 24 ounces This is the null hypothesis.

After taking a sample of 100 boxes, they checked whether or not the machine is filling the boxes worn an average of 24 ounces of cereal.

This is the alternative hypothesis and is written as

H1: u ≠ 24 ( 2 tailed test)

the two may have that, even a breakdown is probably offered

step-by-step explanation:

12: 00 p.m. to 7: 00 p.m. is a total of 7 hours.

4: 00 p.m. to 7: 00 p.m. is a total of 3 hours.

this means that from 4: 00 p.m to 7: 00 p.m. this represents 3/7 of what was lost from 12: 00 p.m. to 7: 00 p.m.

after knowing this, after doing 11,600 - 6,800 = 4,800

4,800 represents 3/7 of what was lost for 7 hours.

we then divide 4,800 by 3 which gets 1,600.

because we know that 1,600 represents 1/7 of how much water was lost, we just have to multiply by 7, which gets 11,200.   after adding 11,200 to how much water was left at 7: 00 p.m. which was 6,800. 11,200 + 6,800 = 18,000

this means that the pool originally had 18,000 gallons in the pool.

you can also check your work by doing 18,000 - 4(1600), which becomes           1800 - 6400 which gets you 11,600.
