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
