By pythagoreans' theorem,

Longer edge
= √(2² + 6²)
= √40

∴ The length of the longer edge is the square root of 40 feet.

Shorter edge
= √(1² + 3²)
= √10

Area = L × B
= √40 × √10
= 20 feet²

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
