Alecsey [184]

Answer:

A. III only

Explanation:

One of the very useful tools in project management analysis is the PERT and CPM.

PERT (Program evaluation and review technique) provides valuable information regarding which activities need to be closely watched.

While CPM (Critical Path Method) helps in determining the time required to complete each task, and the minimum time required to complete a project.

Both CPM and PERT serve similar purposes by helping to determine projects or activities that need to be watched closely.

Jupiter Explorers has $7,800 in sales. The profit margin is 4 percent. There are 6,100 shares of stock outstanding, with a price
Law Incorporation [45]

Answer:

The company's price–earnings ratio is 36.

Explanation:

Price earning ratio is the ratio of market value of share to earning per share. It shows that how much investors are willing to pay for each dollar of earning of the company.

Profit margin = Net income / sales

0.04 = Net Income / $7800

Net Income = $7800 x 0.04 = $312

Earning Per share = Net Income / number of outstanding shares

Earning Per share = $312 / 6,100 = $0.05

Price earning ratio = Market price of share / Earning per share

Price earning ratio = $1.8 / $0.05 = 36

The Centers for Disease Control and Prevention (CDC) defines a healthy sleep duration
laiz [17]

a. The point estimate of the married people that sleep well is = 0.6299. The confidence interval for the mean hours of sleep for those that have never been married but report good sleep is 0.6186, 0.6412

b. The point estimate of the number of hours for people that have never been married = 7.2257

95% confidence interval for the mean number of  hours of sleep for those who have never been married = 7.2065, 7.2447

c. the estimated number of sleep for those that have never been married = 7.729 hours

a. The point estimate

P=\frac{Xp}{n}

Xp = successes\\n = sample size\\

Those who have never been married n = 7044

Xp = those who sleep for 7 hours at least

To get Xp, the <u>excel function </u>

Countif(range, criteria)

Countif(A:A, >=7)

This gives Xp = 4437

Point estimate =

\frac{4477}{7044}

= 0.6299

The point estimate of the married people that sleep well is = 0.6299

At 95% interval of confidence,

α = 1-0.95 = 0.05

α/2 = 0.05/2 = 0.025

Z0.025 = 1.96 ( Use the standard probability normal table)

Margin of Error

=M.E = 1.96\sqrt \frac{0.6299(1-0.6299)}{7044} \\\\= 1.96\sqrt{0.000033} \\\\1.96*0.0057

= 0.0113

The 95% confidence interval

= 0.6299 - 0.0113 , 0.6299 + 0.0113

= 0.6186, 0.6412

The confidence interval for the mean hours of sleep for those that have never been married is 0.6186, 0.6412

b. Sample mean

x = ∑x/n

x = number of sleep of the never been married

Mean is calculated using excel function

Average(range)

Average(a:a)

This gives the sample mean = 7.2257

The point estimate of the number of hours for people that have never been married = 7.2257

<u>Standard deviation</u> using excel =

Stdev(A:A) = 0.8211

Margin of error =1.96*\frac{0.8211}{\sqrt{7044} }

= 0.0192

The<u> confidence interval</u> =

= 7.2257-0.0192, 7.2257+0.0192

= 7.2065, 7.2447

95% confidence interval for the mean number of  hours of sleep for those who have never been married = 7.2065, 7.2447

c. From the available data, the mean number of sleep per day that is gotten from the 4437 people that are unmarried and sleep healthily for at least 7 hours = 34295.1

Mean = 34295.1/4437

= 7.729

the estimated number of sleep for those that have never been married = 7.729 hours
