The effects of smoking on human performance was investigated using three tasks that differed in the level of cognitive processing that was required to perform them, with different participants serving in each task.

Pattern recognition task - participants had to locate a target on a screen

Cognitive task - participants were required to read a passage and then recall it at a later time

Driving simulation video game

In each case the dependent variable was the number of errors that the participant committed.

Participants were further divided into three Smoking groups

Group AS was composed of people who actively smoked during or just before carrying out the task.

Group DS participants were regular smokers who had not smoked for 3 hours before the task (D stands for delay).

Group NS were nonsmokers.

Compute a 3 (Smoking Group) x 3 (Task) ANOVA

Can one of you PLEASE explain how to put the 3 dependent variables into one column in SPSS?? I don't need help with the analysis.

1. An impartial judge of a local garden competition collects scores from two groups of judges on what he suspects to be the number one garden. He finds the first group (n = 5) has a mean score of 76. The second group (n = 3) has a mean score of 91. So that he may declare the final score, what is the weighted mean of these two groups?

2. A social scientist measures the number of minutes (per day) that a small hypothetical population of college students spends online. Student Score Student Score A 94 F 96 B 88 G 25 C 74 H 61 D 88 I 82 E 98 J 98

(a) What is the range of data in this population? min

(b) What is the IQR of data in this population? min

(c) What is the SIQR of data in this population? min

(d) What is the population variance?

(e) What is the population standard deviation? (Round your answer to two decimal places.) min

3. A sociologist records the annual household income (in thousands of dollars) among a sample of families living in a high-crime neighborhood. Locate the lower, median, and upper quartiles for the times listed below. Hint: First arrange the data in numerical order.

a) lower quartile thousand dollars

b) median thousand dollars

c) upper quartile thousand dollars

Cook Farm Supply Company manufactures and sells a pesticide called Snare. The following data are available for preparing budgets for Snare for the first 2 quarters of 2020.

Your assistant has prepared two budgets: (1) the manufacturing overhead budget shows expected costs to be 125% of direct labor cost, and (2) the direct materials budget for Tarr shows the cost of Tarr purchases to be $299,000 in quarter 1 and $425,500 in quarter 2.

Question 4

The following is a Binomial Option Pricing Model question. There will be 7 questions asked about it. Since the order of questions chosen is random, I suggest you solve the following all at once and choose your answer to each part as it comes up.

You will be asked the following questions:

1. What are the values of the calls at maturity, t=2?

2. What are the values of the calls at t =1?

3. What is the initial (t = 0) fair market price of the call?

4. What is the initial (t = 0) hedge ratio?

5. What are the hedge ratios at t = 1?

6. If one call was written initially, what is the value of the hedged portfolio one period later (t = 1)?

7. If the stock moves down in period 1 how would you adjust your t = 0 hedge by trading only stock?

We have a 2-state, 2-period world (i.e. t = 0, 1, 2). The current stock price is 100 and the risk-free rate each period is 5%. Each period the stock can either go up by 10% or down by 10%. A European call option on this stock with an exercise price of 90 expires at the end of the second period.

What are the values of the calls at t =1? (closest answer)

Q1. (b) Two operators have taken three measurements for each of 10 parts number during a gauge capability study as shown in Table 1.

(i)        Does the control chart analysis of the data indicate any potential problem in using the gauge?

  (ii)       Determine the standard deviation of the measurement error.
