astra-53 [7]

Answer:

When Aria sold her house after eleven years it worth was <u>$95,300</u>.

Step-by-step explanation:

Given:

Aria paid $75,000 for her house. Its property value increased by 2.2% per year.

Now, to find the worth of Aria house when sold after eleven years.

Let the amount of house after eleven years be x.

Amount Aria paid for her house (A) = $75,000.

Rate of property increased per year (r) = 2.2%.

Time (t) = 11 years.

Now, to get the amount of house after eleven years we put formula:

x=A\times (1+\frac{r}{100})^{11}

x=75000\times (1+\frac{2.2}{100})^{11}

x=75000\times (1+0.022)^{11}

x=75000\times (1.022)^{11}

x=75000\times 1.2704

x=95280.

<em>The amount of house after eleven years to the nearest hundred dollars is $95,300.</em>

Therefore, when Aria sold her house after eleven years it worth was $95,300.

A company claims that less than 10% of adults own a smart watch. You want to test this claim, and you find that in a random samp
Nezavi [6.7K]

Answer:

Test statistic is 0.67

Critical value is -2.33

Step-by-step explanation:

Consider the provided information.

The formula for testing a proportion is based on the z statistic.

z=\frac{\hat p-p_0}{\sqrt{p_0\frac{1-p_0}{n}}}

Were \hat p is sample proportion.

p_0 hypothesized proportion and n is the smaple space,

Random sample of 100 adults, 12% say that they own a smart watch.

A company claims that less than 10% of adults own a smart watch.

Therefore, n = 100  \hat p = 0.12 , P_0 = 0.10

1 - P_0 = 1 - 0.10 = 0.90

Substitute the respective values in the above formula.

z=\frac{0.12-0.10}{\sqrt{0.10\frac{0.90}{100}}}

z\approx 0.67

Hence, test statistic = 0.67

This is the left tailed test.

Now using the table the P value is:

P(z < 0.667) = 0.7476

P-value = 0.7476

\alpha = 0.01

Here,  P-value > α therefore, we are fail to reject the null hypothesis.

Z_{\alpha}= Z_{0.01} = -2.33

Hence, Critical value is -2.33
