Let x be a random variable that represents the weights in kilograms (kg) of healthy adult female deer (does) in December in a national park. Then x has a distribution that is approximately normal with mean μ = 60.0 kg and standard deviation σ = 8.6 kg. Suppose a doe that weighs less than 51 kg is considered undernourished.

(a) What is the probability that a single doe captured (weighed and released) at random in December is undernourished? (Round your answer to four decimal places.)


(b) If the park has about 2900 does, what number do you expect to be undernourished in December? (Round your answer to the nearest whole number.)
does

(c) To estimate the health of the December doe population, park rangers use the rule that the average weight of n = 65 does should be more than 57 kg. If the average weight is less than 57 kg, it is thought that the entire population of does might be undernourished. What is the probability that the average weight x for a random sample of 65 does is less than 57 kg (assuming a healthy population)? (Round your answer to four decimal places.)


(d) Compute the probability that x< 61 kg for 65 does (assume a healthy population). (Round your answer to four decimal places.)


Suppose park rangers captured, weighed, and released 65 does in December, and the average weight was x= 61 kg. Do you think the doe population is undernourished or not? Explain.

Since the sample average is above the mean, it is quite likely that the doe population is undernourished.

Since the sample average is above the mean, it is quite unlikely that the doe population is undernourished.    

Since the sample average is below the mean, it is quite likely that the doe population is undernourished.

Since the sample average is below the mean, it is quite unlikely that the doe population is undernourished.

Let x be a random variable that represents the weights in kilograms (kg) of healthy adult female deer (does) in December in a national park. Then x has a distribution that is approximately normal with mean μ = 52.0 kg and standard deviation σ = 9.0 kg. Suppose a doe that weighs less than 43 kg is considered undernourished.

(c) To estimate the health of the December doe population, park rangers use the rule that the average weight of n = 70 does should be more than 49 kg.

for a random sample of 70 does is less than 49 kg (assuming a healthy population)? (Round your answer to four decimal places.)

< 53.6 kg for 70 does (assume a healthy population). (Round your answer to four decimal places.)

An article in the Wall Street Journal on the parking problems at​ Tesla's Fremont, California factory notes​ that: "Tesla has tried to encourage alternatives to​ driving, such as​ biking, public transportation and the shuttle buses provided from around the Bay Area​ ..."

If Tesla auctioned off the right to park in its​ lot, would the firm need to provide other encouragement for employees to use alternative means of​ transportation? Briefly explain.

A.

​Yes, it would remain necessary to provide alternatives to driving because the price of parking spaces would rise.

B.

​No, it would not be necessary because the spaces would be allocated to those most willing to pay for them.

C.

​No, encouraging the use of transportation alternatives would not be necessary due to a shortage of spaces.

D.

​Yes, encouraging driving alternatives would still be necessary because the supply of spaces would be unchanged.

Is the most economically efficient allocation of parking spaces in​ Tesla's lot likely to result from auctioning off the right to park or from keeping parking free while encouraging employees to use alternative means of getting to​ work? Briefly explain.

A.

Keeping parking​ free, because no one has to pay anything for parking.

B.

Keeping parking​ free, because those with less income may get a parking space.

C.

Auctioning off the right to​ park, because the people who get the parking spaces would be determined randomly.

D.

Auctioning off the right to​ park, because those who benefit the most from the parking spaces would receive them.

Given your answer​ above, why​ hasn't Tesla considered charging employees for parking in its​ lot?

A.

Employees may consider this method to be unfair.

B.

Tesla workers are not rational.

C.

Managers may believe that they should not be charged for parking.

D.

Charging employees for parking is too​ time-consuming.

Bank USA offers a semiannual interest rate of 0.7%, what is the APR (annual percentage rate)?

A. 0.700%

Based on the investment portfolio information shown below, what is the portfolio’s beta?

4. If a drop in government spending of $ 2 billion produces a drop in the economy's real GDP of $ 10 billion, what is the value of that country's PMC?

a. Both the marginal propensity to consume and the multiplier is 0.2
b. The multiplier is 0.2.
c. The multiplier is 5.0.
d. The slope of the GA curve is 0.2.

6. All of the following statements about equilibrium spending are true except:

b. The planned aggregate expense equals the actual expense.
c. Planned aggregate spending equals real GDP.
d. The effective investment is less than the planned investment.

DataSpan, Inc., automated its plant at the start of the current year and installed a flexible manufacturing system. The company is also evaluating its suppliers and moving toward Lean Production. Many adjustment problems have been encountered, including problems relating to performance measurement. After much study, the company has decided to use the performance measures below, and it has gathered data relating to these measures for the first four months of operations.

Management has asked for your help in computing throughput time, delivery cycle time, and MCE. The following average times have been logged over the last four months:

Required:

1-a. Compute the throughput time for each month.

1-b. Compute the delivery cycle time for each month.

1-c. Compute the manufacturing cycle efficiency (MCE) for each month.

2. Evaluate the company’s performance over the last four months.

3-a. Refer to the move time, process time, and so forth, given for month 4. Assume that in month 5 the move time, process time, and so forth, are the same as in month 4, except that through the use of Lean Production the company is able to completely eliminate the queue time during production. Compute the new throughput time and MCE.

3-b. Refer to the move time, process time, and so forth, given for month 4. Assume in month 6 that the move time, process time, and so forth, are again the same as in month 4, except that the company is able to completely eliminate both the queue time during production and the inspection time. Compute the new throughput time and MCE.
