So your equation is 
. You need to simplify this answer.
So first off, do 2x times 2x.
2 x 2 = 4.
Your equation is now
You're already off to a great start, so now let's add 4x + 7x. It is 11x.
Your equation is almost done! It's
right now.
Divide both sides by 11, and your answer is...
0.36363636 and so on, or you can round to the nearest hundreth, in which it will be
0.36.
I hope I helped!

Answer:
Reject H0 since test statistic <-2.492
Step-by-step explanation:
Given that the American Water Works Association reports that the per capita water use in a single-family home is 74 gallons per day.
n = 25
x bar = 69
s= 8.3
std error = s/sqrt n =
H0:
Ha:
(Left tailed test at 5% significance level)
a) Reject H0 if t-2.492
b) Test statistic = mean difference/std error
=
=-3.01
df =24
c) Reject H0
