Answer:
Multiply everything by 15 because when you divide 40 from 600 you get 15. We will only use the 2 numbers on the right of both samples. Then find the total of each row
<u>18 turns into 270| 10 truns into 150 </u>=420
<u>19 turns into 285| 7 turns into 105</u>=390
Headline A: Both samples show that over 300 students want to go after 8 am which makes the headline true.
Headline B: 8:30 is actually the most popular start time because both samples show greater amount of students choose 8:30 as the start time than any other time.
Headline C: This statement is not supported by the data, the data shows that 7:45 am is the second most popular selection.
Headline D: This statement is not supported by the data because both samples show that over 100 people chose 9:00.
I hope this is a good answer for you and I hope you have a nice day.
P.S. Please mark me braineast!
The difference between a population distribution and sampling a distribution
Definition: The Population Distribution is a form of probability distribution that measures the frequency with which the items or variables that make up the population are drawn or expected to be drawn for a given research study.
Defintion: The Sampling Distribution is a form of probability of a random sample out of a group of frequency which is made up of the sample of which the population has been picked out of, making it a partial research study
PART A
Coefficient
Coefficient h is 7.50
Coefficient s is 0.20
Variable
h and s
Constant
40
PART B
7.50h + 0.20s + 40
= 7.50(25) + 0.20(300) + 40
= 187.5 + 60 + 40
= 287.5
She earns $287.5
PART C
Yes, the coefficient of h would change to 9, the rests are still the same. Because she's no longer receive 7.50 per hour, and start earning 9 per hour, so the coefficient should change.
The expression would be
9h + 0.20s + 40
