The American Water Works Association reports that the per capita water use in a single-family home is 74 gallons per day. Legacy
Lunna [17]

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 = \frac{8.3}{5} \\=1.66

H0:\bar x = 74

Ha: \bar x

(Left tailed test at 5% significance level)

a) Reject H0 if t\leq-2.492

b) Test statistic = mean difference/std error

= \frac{69-74}{1.66} \\=-3.012\\

=-3.01

df =24

c) Reject H0
