Consider the population that consists of all employees of a large computer manufacturer.
a. Give an example of a question about this population that could be answered by collecting data and using it to estimate a population characteristic. (Select all that apply.)
1. What proportion of employees packs their lunch on Mondays?
2. Are more than half of the employees married?
3. What is the average commute time of employees at the company? 4. Who is the oldest employee at the company?
5. Do more than one-tenth of the employees drive hybrid vehicles?
6. What proportion of employees has computers at home?
b. Give an example of a question about this population that could be answered by collecting data and using it to test a claim about this population. (Select all that apply.)
1. Which employee has the longest commute time?
2. What proportion of employees is left-handed?
3. Do more than 20% of employees have children?
4. Are less than half of the employees women?
5. Do more than half of the employees have computers at home? 6. What is the average age of employees at the company?

Step-by-step explanation:

(a)  Options 1 , 3 and 6 are correct. Reason being that in these options, we are trying to estimate either the population proportion or the population mean.

(b) Options 3 , 4 and 5are correct. Reason being that in these optionswe are trying to test a hypothesis regarding the population proportion.

answer: sorry but i need points

step-by-step explanation:

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.
