Over the past several years, the proportion of one-person households has been increasing. The Census Bureau would like to test t

Ganezh [65]

Answer: z =2.39

Step-by-step explanation:

Given :

$H_0: p \leq0.23\\\\ H_a: p > 0.23$

A random sample of 136 households found that 43 consisted of one person.

i.e. Sample size : n= 136

Sample proportion : $\hat{p}=\dfrac{43}{136}=0.316176470588\approx0.3162$

Test statistic for proportion :-

$z=\dfrac{\hat{p}-p}{\sqrt{\dfrac{p(1-p)}{n}}}$

$\Rightarrow z=\dfrac{0.3162-0.23}{\sqrt{\dfrac{0.23(1-0.23)}{136}}}\\\\\Rightarrow\ z=\dfrac{0.0862}{\sqrt{0.00130220588235}}\\\\\Rightarrow\ z=\dfrac{0.0862}{0.0360860898734}\\\\=2.38873206552\approx2.39$

Hence, the value of the test statistic: z =2.39

Robert wants to buy an oven that costs 1000$ including taxes. , to pay for the oven, he will use a payment plan. He makes a down

natka813 [3]

Answer:

15% increase

Step-by-step explanation:

If Robert uses the payment plan then he will pay"

Down Payment - $250

6 months of 150 - 6*$150 = 900

In total he pays $1150.

To find the percent increase/decrease:

1. Subtract the original value from the new value.

2. Divide by the original value.

3. Multiply the decimal by 100 to convert to a percent.

1150 - 1000 = 150

150/1000 = 0.15

0.15*100 = 15%
