You are the manager of an assembly plant and have determined that the employee of the week would be the one that was the most ef

ficient. Jimmy worked a total of 30 hours and assembled a total of 80 radios, Jordan worked a total of 42 hours and assembled a total of 115 radios and Denise worked a total of 38 hours and assembled a total of 100 radios. To determine the employee of the week you divided the number of radios assembled by the number of hours worked and rewarded the employee that got the highest number. Is this the correct method?

No because Jordan could have rushed working on the radios and the radios couldn't have turned out well. It said the most efficient that means good quality

Answer:

Yes, this is a good method.

Step-by-step explanation:

Since the ratio of the number of radios assembled to the number of hours worked shows the work efficiency of an employee.

Also, the employee who works less hours and assembled more radios are more efficient, that employee knows how to utilize time.

So, Giving the reward to the employee whose ratio is the highest number is the correct method to judge the efficient.

Reil [10]

Answer:

The z score for bolt of diameter 18.12 mm is 1.20.

Step-by-step explanation:

Let <em>X</em> = diameter of bolts.

It is provided that the random variable <em>X</em> follows a Normal distribution with mean, <em>μ</em> = 18 mm and standard deviation, <em>σ</em> = 0.10 mm.

A <em>z</em>-score is a standardized score, a numerical, that defines how far a data value from the mean.

The distribution of <em>z</em>-scores is defined by the Standard Normal distribution.

Z\sim N(0, 1)

The formula to compute the <em>z</em>-score is:

z=\frac{x-\mu}{\sigma}

The value of the diameter of a bolt is, <em>x</em> = 18.12 mm.

Compute the <em>z</em>-score for this value as follows:

z=\frac{x-\mu}{\sigma}=\frac{18.12-18}{0.10}=\frac{0.12}{0.10}=1.20

Thus, the z score for bolt of diameter 18.12 mm is 1.20.

g100num [7]

Answer:

Therefore,  the probability that at least half of them need to wait more than 10 minutes is <em>0.0031</em>.

Step-by-step explanation:

The formula for the probability of an exponential distribution is:

P(x < b) = 1 - e^(b/3)

Using the complement rule, we can determine the probability of a customer having to wait more than 10 minutes, by:

p = P(x > 10)

  = 1 - P(x < 10)

  = 1 - (1 - e^(-10/10) )

  = e⁻¹

  = 0.3679

The z-score is the difference in sample size and the population mean, divided by the standard deviation:

z = (p' - p) / √[p(1 - p) / n]

  = (0.5 - 0.3679) / √[0.3679(1 - 0.3679) / 100)]

  = 2.7393

Therefore, using the probability table, you find that the corresponding probability is:

P(p' ≥ 0.5) = P(z > 2.7393)

<em>P(p' ≥ 0.5) = 0.0031</em>

<em></em>

Therefore,  the probability that at least half of them need to wait more than 10 minutes is <em>0.0031</em>.
