Determine if the finite correction factor should be used. if so, use it in your calculations when you find the probability. in a sample of 700 gas stations, the mean price for regular gasoline at the pump was $ 2.837 per gallon and the standard deviation was $0.009 per gallon. a random sample of size 55 is drawn from this population. what is the probability that the mean price per gallon is less than $2.834?

0.9932

Step-by-step explanation:

Given : Mean :

Standard deviation :

a) The formula for z -score :

Sample size = 55

For x= $2.834 ,

The p-value =

Thus, the probability that the mean price per gallon is less than $2.834 is approximately 0.9932 .

81 seats

step-by-step explanation:

if you multiply 0.65 times 125 then you get 81.5 seats. well since you can't have half of a seat you have to round down and get 81 seats in the no children zones. that leave 44 seats outside of the no children zone.

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
