Steph runs a vehicle body repair shop with one mechanic in Cleveland. Repair time for vehicles is exponentially distributed, wit

h a mean of 2.8 minutes per vehicle. Customers arrive at an average rate of 15 per hour following a Poisson distribution. NOTE: calculate the measures per hour. Calculate system utilization. (Round your answer to the nearest whole percent without the percent sign.) System Utilization =

Answer:

System utilization = 0.7 or 70%

Step-by-step explanation:

Given arrival rate of customer = 15 customer/Hour

Servie rate = \dfrac{60}{2.8} customer/Hour

Now, use the below formula to find the system utilization.

System utilization = \dfrac{\text{ Arrival rate of customer }}{\text{ Servie rate}}

System utilization = \dfrac{15}{ \dfrac{60}{2.8}}

System utilization = \dfrac{15}{ \dfrac{60}{2.8}}

System utilization = 0.7 or 70%

For a test of population proportion H0: p = 0.50, the z test statistic equals 1.05. Use 3 decimal places. (a) What is the p-valu
sergiy2304 [10]

Answer:

(a) The <em>p</em>-value of the test statistic is 0.147.

(b) The <em>p</em>-value of the test statistic is 0.294.

(c) The <em>p</em>-value of the test statistic is 0.8531.

(d) None of the <em>p</em>-values give strong evidence against the null hypothesis.

Step-by-step explanation:

The <em>p</em>-value is well defined as the probability,[under the null hypothesis (H₀)], of attaining a result equivalent to or greater than what was the truly observed value of the test statistic.

We reject a hypothesis if the p-value of a statistic is lower than the level of significance <em>α</em>.

The null hypothesis for the test of population proportion is defined as:

<em>H₀</em>: <em>p</em> = 0.50

The value of <em>z</em>-test statistic is,

<em>z</em> = 1.05

(a)

The alternate hypothesis is defined as:

<em>Hₐ</em>: <em>p</em> > 0.50

Compute the <em>p</em>-value of the test statistic as follows:

p-value=P(Z>1.05)\\=1-P(Z

*Use a <em>z</em>-table for the probability value.

Thus, the <em>p</em>-value of the test statistic is 0.147.

(b)

The alternate hypothesis is defined as:

<em>Hₐ</em>: <em>p</em> ≠ 0.50

Compute the <em>p</em>-value of the test statistic as follows:

p-value=2\times P(Z>1.05)\\=2\times 0.1469\\=0.2938\\\approx 0.294

*Use a <em>z</em>-table for the probability value.

Thus, the <em>p</em>-value of the test statistic is 0.294.

(c)

The alternate hypothesis is defined as:

<em>Hₐ</em>: <em>p</em> < 0.50

Compute the <em>p</em>-value of the test statistic as follows:

p-value= P(Z1.05)=1- 0.1469\\=0.8531

*Use a <em>z</em>-table for the probability value.

Thus, the <em>p</em>-value of the test statistic is 0.8531.

(d)

The decision rule of the test is:

If the <em>p</em>-value of the test is less than the significance level <em>α</em>, then the null hypothesis is rejected at <em>α</em>% level of significance.

And if the <em>p</em>-value of the test is more than the significance level <em>α</em>, then the null hypothesis is failed to be rejected.

The most commonly used level of significance are:

<em>α</em> = 0.01, 0.05 and 0.10

The <em>p</em>-value for all the three alternate hypothesis are:

<em>p-</em>values = 0.147, 0.294 and 0.8531.

All the <em>p</em>-values are quite large compared to the <em>α</em> values.

Thus, none of the <em>p</em>-values give strong evidence against the null hypothesis.

The null hypothesis was failed to be rejected.
