Iconic memory is a type of memory that holds visual information for about half a second (0.5 seconds). To demonstrate this type of memory, participants were shown three rows of four letters for 50 milliseconds. They were then asked to recall as many letters as possible, with a 0-, 0.5-, or 1.0-second delay before responding. Researchers hypothesized that longer delays would result in poorer recall. The number of letters correctly recalled is given in the table.

(a) Complete the F-table. (Round your values for MS and F to two decimal places.)

(b) Compute Tukey's HSD post hoc test and interpret the results. (Assume alpha equal to 0.05. Round your answer to two decimal places.)

The critical value is_______ for each pairwise comparison.

Which of the comparisons had significant differences? (Select all that apply.)

A.) The null hypothesis of no difference should be retained because none of the pairwise comparisons demonstrate a significant difference.

B.) Recall following no delay was significantly different from recall following a half second delay.

C.) Recall following a half second delay was significantly different from recall following a one second delay.

D.) Recall following no delay was significantly different from recall following a one second delay.

1. Assume that a company has two cost drivers—number of courses and number of students. The planned number of courses and students were 5 and 100, respectively. The actual number of courses and students were 6 and 110, respectively. One of the company’s expenses is influenced by both cost drivers and it has a fixed element as well. Its cost formulas are $50 per course, $5 per student, and $1,000 per period. The total actual amount of this expense is $1,880. The spending variance for this expense would be:

a. 30 U

b. $30 F

c. $130 F

d. $130 U

2. Assume that a company provided the following cost formulas for three of its expenses (where q refers to the number of hours worked):

The company’s planned level of activity was 2,000 hours and its actual level of activity was 1,900 hours. If these are the company’s only three expenses, what total amount of expense would appear in the company’s flexible budget?

a. $12025

b. $12175

c. $12650

d. $12250

Prepare a cash budget, properly labeled and in good accounting order, for October based on the following:

Forecast sales

July                 $150,000           Credit sales are 40% of total sales and are collected

August           $170,000            as follows: 20% one month after the sale, 30%

Sept.              $180,000           two months after the sale and 50% three months

Oct                 $190,000           after the sale

Accounts payable are paid as follows: 70% one month after the purchase and 30% two months after the purchase.   Rent is $1,500 per month and utilities are $700 per month.

In October, the firm will have an insurance payment due of $450.

Expected Accounts Payable

August                     $170,000                  

Sept                         $175,000                  

Oct.                          $180,000

Beginning cash for October is $3,200

You are considering investing $2,300 in a complete portfolio. The complete portfolio is composed of Treasury bills that pay 4% and a risky portfolio, P, constructed with two risky securities, X and Y. The optimal weights of X and Y in P are 60% and 40% respectively. X has an expected rate of return of 14%, and Y has an expected rate of return of 12%. To form a complete portfolio with an expected rate of return of 8%, you should invest approximately __________ in the risky portfolio. This will mean you will also invest approximately __________ and __________ of your complete portfolio in security X and Y, respectively. *No correlation given*

Multiple Choice

• 50%; 30%; 20%

• 43%; 26%; 17%

• 0%; 60%; 40%

• 26%; 46%; 28%

Consider the following two​ projects:

Project    Year 0 Cashflow   Year 1 Cashflow    Year 2 Cashflow    Year 3 Cashflow   Year 4 Cashflow Discount rate

A    -100 40 50 60 N/A .15

B -147   50 70 90 5 .15

An incremental IRR of Project B over Project A is _________%.

(Please round to two decimal places, write the number only without "%". i.e. if the answer is "5%", write "5.00")

Alphabetic Telephone Number Translator

          Many companies use telephone numbers like 555-GET-FOOD so the number is easier for their customers to remember. On a standard telephone, the alphabetic letters are mapped to numbers in the following fashion:

A, B, and C = 2

            D, E, and F = 3

            G, H, and I = 4

            J, K, and L = 5

            M, N, and O = 6

            P, Q, R, and S = 7

            T, U, and V = 8

            W, X, Y, and Z = 9

For your program, you will be using a secret code as show below:

A and C = 2

            D and E = 3

            B, G, H, and I = 4

            J, K, L, and X = 5

            F, M, N, O, and P = 6

            Q = 7

            R, S, T, U, and V = 8

            X, Y, and Z = 9

            Write a program that asks the user to enter a 10-character telephone number in the format XXX-XXX-XXXX (where X can be an upper- or lower-case letter or a number).

• The program should display the telephone number with any alphabetic characters that appeared in the original translated to their numeric equivalent. For example, if the user enters 555-get-GOOD the application should display 555-438-4663.
• Your program should have good internal documentation, use methods and be user friendly.
• Make sure that when the user runs the program, they understand how to enter the telephone number – be extremely user friendly.

In 2014, 15% of women 40-44 years of age have never given birth. A women’s health magazine conducts a more recent survey with a sample of 250 adult women 40-44 years of age. They found that 17.2% of the respondents have never given birth. An editor sees this result and believes that the proportion of women 40-44 years of age who have not given birth has increased since 2014. (Note: A labelled diagram and proper notation are required for part a).)
a) What is the probability that in a random sample of 250 adult women 40-44 years of age, more than 17.2% indicate they have never given birth? Interpret this probability.
b) Do you believe the editor is correct in claiming that the proportion of women 40-44 years of age who have not given birth has increased since 2014? Explain your answer using the result from part a)

Strickler Technology is considering changes in its working capital policies to improve its cash flow cycle. Strickler's sales last year were $3,410,000 (all on credit), and its net profit margin was 7%. Its inventory turnover was 6 times during the year, and its DSO was 31 days. Its annual cost of goods sold was $1,800,000. The firm had fixed assets totaling $530,000. Strickler's payables deferral period is 34 days. Assume 365 days in year for your calculations. Do not round intermediate calculations. Calculate Strickler's cash conversion cycle. Round your answer to two decimal places. days Assuming Strickler holds negligible amounts of cash and marketable securities, calculate its total assets turnover. Round your answer to two decimal places. x Calculate its ROA. Round your answer to two decimal places.

% Suppose Strickler's managers believe the annual inventory turnover can be raised to 8 times without affecting sale or profit margins.

What would Strickler's cash conversion cycle have been if the inventory turnover had been 8 for the year? Round your answer to two decimal places. days

What would Strickler's total assets turnover have been if the inventory turnover had been 8 for the year? Round your answer to two decimal places.

x What would Strickler's ROA have been if the inventory turnover had been 8 for the year? Round your answer to two decimal places. %
