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

You have ​$23 comma 000 to​ invest, part at 8 % and the rest at 9 %. If x is the amount invested at 8 %​, write an algebraic exp
Vinvika [58]

<em>x</em> = amount invested at 8 %. Then 23 000 - <em>x</em> = amount invested at 9 %

Annual income (<em>I</em>) = interest at 8 % + interest at 9 %

<em>I</em> = 0.08<em>x</em> + 0.09(23 000 – <em>x</em>)

<em>I</em> = 0.08<em>x</em> + 2070 – 0.09<em>x</em>

<em>I</em> = 2070 – 0.01<em>x</em>
