The proportion of students at a college who have GPA higher than 3.5 is 19%. a. You take repeated random samples of size 25 from

that college and find the proportion of student who have GPA higher than 3.5 for each sample. What is the mean and the standard error of the sampling distribution of the sample proportions?

Step-by-step explanation: The mean and standard error of the sampling distribution of the sample proportions is given by - where p represents the population proportion and n is the sample size. Given: The percentage of students at a college with a GPA exceeding 3.5 is 19%. Thus, p = 19% = 0.19. For a sample size of n = 25, the mean and standard error of that sampling distribution will be: Hence, the mean and standard error of the sampling distribution of sample proportions.

A rectangular prism must have a base with an area of no more than 27 square meters. The width of the base must be 9 meters less
Leona [12618]

Answer:

The upper limit for the height of the prism is 12\ m

Step-by-step explanation:

Let

x------> represent the height of the prism

It is known that

the area of the base of the prism must not exceed

A=L*W

A\leq 27\ m^{2}

thus

L*W\leq 27 -------> inequality A

W=x-9 ------> equation B

L=W+6 -----> equation C

Insert equation B into equation C

L=(x-9)+6

L=x-3 ------> equation D

Substituting equations B and D into inequality A

(x-3)*(x-9)\leq 27-------> using a graphing tool to solve the inequality

The resultant solution for x lies in the interval---------->[0,12]

consult the attached figure

but bear in mind that

The width of the base must be 9 meters shorter than the height of the prism

thus

the solution for x is confined to the interval ------> (9,12]

The maximum height of the prism equals 12\ m

Svet_ta [12734]

Response:

The Work In Progress (WIP) limit is set at 0.50 days.

Detailed explanation:

Calculating WIP limits:

first, it is essential to determine the efficiency of the process and procedure, which can be calculated as follows:

Value Added Time = 12 days (arrival time)

Non-Value-Added Time = 12 days (departure time)

Efficiency = Value Added / (Value Added + Non-Value Added)

                = 12 / (12+12)

                = 12 / 24

               = 0.50 or 50%

the minimum required throughput time is 0.25 days to achieve the maximum profits

WIP limit = Throughput time / Efficiency

               = 0.25 / 50%

               = 0.50 days.

The WIP limit is 0.50 days.
