Ms. Van Dorn, a 19-year-old female student from Holland, visits the college health center for “being tired all the time.” The nurse notes that she is pale with cool skin, mucous membranes are pale and moist, and lungs are clear. Ms. Van Dorn states that she does get short of breath climbing the stairs or walking uphill. Laboratory results;

RBC 3.8 million µL

HGB 9.8 g/dL

HCT 37%

MCV 70 fL

MCH 25 pg

MCHC 300 g/L

WBC 6000/mm³

Her blood smear is abnormal

1.    How should the nurse interpret these findings?

2.   What questions should the nurse ask Ms. Van Dorn to help in differentiating the type of anemia?

Yoonie is a personnel manager in a large corporation. Each month she must review 16 of the employees. From past experience, she has found that the reviews take her approximately 4 hours each to do with a population standard deviation of 1.6 hours. Let X be the random variable representing the time it takes her to complete one review. Assume X is normally distributed. Let X be the random variable representing the mean time to complete the 16 reviews. Assume that the 16 reviews represent a random set of reviews. Find the probability that the mean of a month's reviews will take Yoonie from 3.8 to 4.2 hrs.

(b) Express the probability statements for the sample mean as well as for the standard normal Z and find the probability. Use four decimal places.

P(__3.8__<X<__4.2__)=

P(___<Z<_____)=_____

1. A lawyer travels daily from his home (in the suburbs) to his office in the city center. On average, the journey takes 24 minutes with a standard deviation of 3.8 minutes. Assume that the distribution of transfer times are normally distributed.

1. if the office opens at 9:00 a.m. and he leaves at 8:45 a.m. What percentage of the time are you late to work daily?
2. If you leave home at 8:35 a.m. and coffee is served in the office between 8:50 and 9 a.m., what is the probability that you will be served coffee?
3. Find the period above which is the 15% of the slowest transfers.
4. Suppose a sample of 5 trips taken by the lawyer is taken. If the attorney always leaves your home at 8:30 a.m., find the probability that on at least 2 trips he arrived between 9:05 a.m. and 9:20 a.m.

State tax allocation problem

Beach Hut is based in Georgia and has stores in Florida. Georgia has a 3.8% corporate tax rate, Florida is 17%.

Because it is a seasonal operation, Beach Hut sells all merchandise at end of season for 40% of manufacturer’s list price to a discount jobber. There are no opening or closing inventories.

All merchandise is ordered by the Georgia office.

Financial reports show the following activity for 2017.

Purchases 14,000,000

Sales 21,000,000 (16,000,000in Georgia, 5,000,000 in Florida)

Expenses

Executive office rental 150,000

Executive salaries 300,000

Insurance (all properties) 42,000

Georgia stores

Rental 185,000

Utilities 40,000

Salary 160,000

Florida

Rental 27,000

Utilities 8,000

Salary 21,000

For tax reporting, Beach Hut allocates all common expenses based on sales.

Compute Georgia and Florida income based on the above

1) A thermocouple element when taken from a liquid at 50 degrees Celsius and plunged into a liquid at 100 degrees celsius at time equal to zero gave the following e.m.f. values. Determine the 95% response time. Time 0 20 40 60 80 100 120 e.m.f. (mV) 2.5 3.8 4.5 4.8 4.9 5.0 5.0

2) What are the advantages and disadvantages of a plastic film type of potentiometer and when compared with the wired-wound potentiometer.

3) A shaft encoder is to be used with a 50 mm radius tracking wheel to monitor the linear displacement. If the encoder produces 256 pluses per revolution, what will be the number of pulses produced by a linear displacement of 300 mm?.

4) Suggest a sensor that could be used, as part of a control system, to determine the difference in level between two containers. The output is to provide an electrical signal for the control system.

*MiniTab Is Required for this question** Suppose that a precise measuring device for new hair growth has been developed and is used in the experiment described in exercise 1922. The percentages of new hair growth for the 30 pairs of men involved in the experiment were recorded. Do these data allow the chemist to conclude that drug B is more effective?

the chickens of the ornithes farm are processed when they are 20 weeks old. the distribution of their weights is normal with a mean of 3.8 lb. and a standard deviation of 0.6 lb. On your paper draw a normal curve for each situation and write what you typed in the calculator. Answer the following.

a. What proportion of chickens weigh less than 3 pounds? (Round to 4 decimal places.)

b. What proportion of chickens weigh between 3.5 and 4.5 pounds? (Round to 4 decimal places.)

c. What proportion of chickens weigh more than 5 pounds? (Round to 4 decimal places.)

d. 20 percent of the chickens have a weight below what value? (Round to 1 decimal place.)

e. If I randomly select 5 chickens, what is the probability that they have weights with a mean more than 4 pounds? (Round to 4 decimal places)

Plant Food Case

A garden center wishes to determine if there are in fact differences in the effect of three different brands of plant food on the growth of sunflowers and the rank of their effectiveness in promoting growth. To do so, they selected 15 sunflower seedlings at random from the greenhouse and fed 5 of the seedlings with Plant Food A, 5 with Plant Food B, and 5 with Plant Food C. The weekly growth of each seedling was measured in inches and is summarized below.

1. Describe the purpose of the study

3. Explain the method used to set up and conduct the test
4. Describe the results
5. State a conclusion
