False

A derived type is a collection of other types.

True

False

A 2-m-high, 4-m-wide rectangular advertisement panel is attached to a 4-m-wide, 0.15 m-high rectangular concrete block (density = 2300 kg/m³) by two 5-cm-diameter, 4-m-high (exposed part) poles, as shown in the figure. If the sign is to withstand 150 km/h winds from any direction, determine (a) the maximum drag force on the panel, (b) the drag force acting on the poles, and (c) the minimum length L of the concrete block for the panel to resist the winds. Take the density of the air to be 1.3 kg/m³.

Required:

1-a. Compute the predetermined overhead rate based on direct labor-hours.

1-b. Using the predetermined overhead rate and other data from the problem, determine the unit product cost of each product.

2. The company is considering replacing its conventional costing system with an activity-based costing system that would assign its manufacturing overhead to the following four activity cost pools:

Determine the activity rate for each of the four activity cost pools.

3. Using the activity rates and other data from the problem, determine the unit product cost of each product.

Exercise 4-7 Contrast ABC and Conventional Product Costs [LO4-2, LO4-3, LO4-4]

Kunkel Company makes two products and uses a conventional costing system in which a single plantwide predetermined overhead rate is computed based on direct labor-hours. Data for the two products for the upcoming year follow:

These products are customized to some degree for specific customers.

Required:

1. The company's manufacturing overhead costs for the year are expected to be $1,600,000. Using the company's conventional costing system, compute the unit product costs for the two products.

2. Management is considering an activity-based costing system in which half of the overhead would continue to be allocated on the basis of direct labor-hours and half would be allocated on the basis of engineering design time. This time is expected to be distributed as follows during the upcoming year:

Compute the unit product costs for the two products using the proposed ABC system.

(For all requirements, do not round intermediate calculations. Round your final answers to 2 decimal places.)

The CIO of an IT company would like to investigate how a software developer’s work experience (in number of years), professional certifications (number of certificates), and knowledge of various computer languages (number of programming languages) contribute to his/her work performance. The work performance is measured on the scale of 1 to 1000 so that the higher one’s score, the better his/her work performance. He collects data from 20 software developers in his company Years of experience Num of certificates Num of progLang Performance

The Conch Café, located in Gulf Shores, Alabama, features casual lunches with a great view of the Gulf of Mexico. To accommodate the increase in business during the summer vacation season, Fuzzy Conch, the owner, hires a large number of servers as seasonal help. When he interviews a prospective server, he would like to provide data on the amount a server can earn in tips. He believes that the amount of the bill and the number of diners are both related to the amount of the tip. He gathered the following sample information.

a-1. Develop a multiple regression equation with the amount of tips as the dependent variable and the amount of the bill and the number of diners as independent variables and complete the table. (Negative amounts should be indicated by a minus sign. Round your answers to 3 decimal places.)

a-2. Write out the regression equation. (Negative amounts should be indicated by a minus sign. Round your answers to 3 decimal places.)

a-3. How much does another diner add to the amount of the tips? (Round your answer to 2 decimal places.)

b-1. Complete the ANOVA table. (Leave no cells blank - be certain to enter "0" wherever required. Round "SS, MS" to 3 decimal places and "F" to 2 decimal places.)

b-2. What is your decision regarding the null-hypothesis?

c-1. Conduct an individual test on each of the variables. What is the decision rule at the 0.05 level of significance? (Negative amounts should be indicated by a minus sign. Round your answers to 3 decimal places.) c-2. Which variable should be deleted? Use the equation developed in part (c) to determine the coefficient of determination. (Round your answer to 2 decimal places.) State true or false. From the graph the residuals appear normally distributed. True False Choose the right option from the following graph. The residuals look random.

****show spss input***A researcher is interested to learn if the level of interaction a women in her 20s has with her mother influences her life satisfaction ratings. Below is a list of women who fit into each of four levels of interaction. Conduct a One-way ANOVA on the data to determine if there are differences between groups; does the level of interaction influence women’s ratings of life satisfaction? Report the results of the One-way ANOVA. If significance is found, run the appropriate post-hoc test and report between what levels the significant differences were found. Report the test statistic using correct APA formatting and interpret the results.

2. Are handedness and gender related? A researcher collected the following data in hopes of discovering if handedness and gender are independent (Ambidextrous individuals were excluded from the study). Use the Chi-Square test for independence to explore this at a level of significance of 0.05. Report the test statistic using correct APA formatting and interpret the results.
