Suppose that a parking lot replaces the human server who receives payment, with one automated machine that reads the credit-card and receives payments automatically. Assume that customer arrival rates and average service time remain the same. How will waiting time in the queue for payment be affected? Increase, Decrease, Remain the Same? Briefly explain your reasoning.

QUESTION 01

1. Are there some social costs and social benefits associated with the upgrade and investment in human capital? List and then briefly comment on three (3) existing costs and three (3) existing benefits.                                                                                                          [6 marks]
2. In cases where a skill type is highly specific and scarce; what does this suggest about the years of training, the distribution of income, the labour productivity, and the private and social human capital investment cost of the individuals involved?                                     [8 marks]
3. Labour supply elasticities range from very low to very high coefficients, depending on the labour units involved. Use this comment to relate supply elasticities to skill levels and to do a simple analysis of how both low and high supply elasticities determine or relate to the earning power or income distribution of labour.                                                                        [8 marks]
4. With reference to the Cob Webb Model, briefly explain the supply and demand for labour and the distribution of income accruing to a specific occupation that has a highly specific skill. Include all the necessary assumptions but no diagram is necessary.

1(a) Using a driving simulator, a human factors psychologist measured the time to press the brake pedal after a visual alert for younger and older drivers. The mean reaction time for a sample of 20 young drivers was 2.8 sec with a standard deviation of .3 sec, and 3.2 sec for a sample of 18 older drivers with a standard deviation of .4. Compute a 99% confidence interval for the difference between the population means for the two groups using the t-distribution. What is the lower limit?

(b) Using a driving simulator, a human factors psychologist measured the time to press the brake pedal after a visual alert for younger and older drivers. The mean reaction time for a sample of 20 younger drivers was 2.8 sec with a standard deviation of .3 sec, and 3.2 sec for a sample of 18 older drivers with a standard deviation of .4. Compute a 95% confidence interval for the difference between the population means for the two groups using the t-distribution. What is the lower limit?

The length of human pregnancies is approximately normally distributed with mean μ= 266 days and standard deviation σ = 15 days.

(b) Suppose a random sample of 20 pregnancies is obtained. Describe the sampling distribution of the sample mean length of human pregnancies.

(c) What is the probability that a random sample of 20 pregnancies has a mean gestation period of 262 days or less?

(d) What is the probability that a random sample of 40 pregnancies has a mean gestation period of 262 days or less?

(e) What might you conclude if a random sample of 40 pregnancies resulted in a mean gestation period of 262 days or less?

(d) What is the probability that a random sample of 50 pregnancies has a mean gestation period of 260 days or less? What might you conclude if a random sample of 50 pregnancies resulted in a mean gestation period of 260 days or less?

Programming assignment for ENSC 3213

NIM

The program is to be written in Matlab. Program must be liberally commented.

The program is a game played by a human versus the machine.

At the start, the prompt asks the human to enter three non-zero integers. These will constitute how many counters are in each Pile.

The machine then asks who goes first.

A turn consists of selecting a Pile and taking a number of counters from that pile.

For example, if the Piles contain 3, 7 and 12 counters, a legal move consists of taking from 1 to 3 from Pile 1, or 1, 2, … 7 from Pile2 etc.

The object of the game is to be the player to take the last counter(s). So if Piles contain 0 2 0, the player whose turn it is will take 2 from Pile 2 and win.

The program must play and optimal strategy so if it has a winning position it will win the game. If it does not have a winning position it should try to extend the game.

At the end of the game, the program must declare the winner.

Data was collected on annual personal time (in hours) taken by a random selection of 50 women and 55 men employed by a medium-sized company. We know that the data for women and men is normally distributed. The Human Resources Department believes that the amount of personal time used by women is less than the amount of personal time used by men.

The sample of women took an average of 25 hours of personal time with a standard deviation of 4.9 hours. The men took an average of 27.6 hours of personal time with a standard deviation of 4.8 hours. Assuming the population standard deviations are equal, test the Human Resources Departments claim at α = 0.05.

1. State the null (H₀) and alternate (H_A) hypotheses.

2. Check the assumptions

3. Give the test statistic.

4. Give the P-value and the conclusion reached about the null hypothesis based on the P-value.

5. Summarize the final conclusion in the context of the claim.

6. Also construct a 95% confidence interval for the mean difference. Does this confidence interval include the value of 0? Should it? Explain
