An inspector inspects large truckloads of potatoes to determine the proportion p in the shipment with major defects prior to usi

victus00 [196]

Answer:

a) The sample proportion is 0.06.

b) The test statistic is z = -1.89.

c) 0.0294

d) 0.294 < 0.05, which means that there is enough evidence that p is less than 0.1, which means that we reject the null hypothesis, and accept the shipment.

Step-by-step explanation:

The null hypothesis is:

$H_{0} = 0.1$

The alternate hypotesis is:

$H_{1} < 0.1$

The test statistic is:

$z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}$

In which X is the sample mean, $\mu$ is the value tested at the null hypothesis, $\sigma$ is the standard deviation and n is the size of the sample.

a. Calculate the sample proportion p.

200 potatoes, 12 defective.

This means that $p = \frac{12}{200} = 0.06$

The sample proportion is 0.06.

b. Calculate the test statistic.

For a proportion p, we have that:

$\sigma = \sqrt{p(1-p)}$

In this question, since $\mu = 0.1$

$\sigma = \sqrt{0.1}{0.9}$

SRS of 200 means that $n = 200$

$H{0} = 0.1$ means that $\mu = 0.1$ . So

$z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}$

$z = \frac{0.06 - 0.1}{\frac{\sqrt{0.1*0.9}}{\sqrt{200}}}$

$z = -1.89$

The test statistic is z = -1.89.

c. Find the p-value.

Looking at the z-table, $z = -1.89$ has a pvalue of 0.0294, which is the pvalue of this hypothesis test.

d. Given α=0.05 what is your conclusion? Should he reject the shipment?

0.294 < 0.05, which means that there is enough evidence that p is less than 0.1, which means that we reject the null hypothesis, and accept the shipment.
