An investment website can tell what devices are used to access the site. The site managers wonder whether they should enhance the facilities for trading via​ "smart phones", so they want to estimate the proportion of users who access the site that way​ (even if they also use their computers​ sometimes). They draw a random sample of

200200

investors from their customers. Suppose that the true proportion of smart phone users is

3737​%.

​a) What would the standard deviation of the sampling distribution of the proportion of the smart phone users​ be?

. 034.034

​(Round to three decimal places as​ needed.)

​b) What is the probability that the sample proportion of smart phone users is greater than

0.370.37​?

. 5.5

​(Round to three decimal places as​ needed.)

​c) What is the probability that the sample proportion is between

0.320.32

and

0.420.42​?

. 858.858

​(Round to three decimal places as​ needed.)

​d) What is the probability that the sample proportion is less than

0.300.30​?

. 02.02

​(Round to three decimal places as​ needed.)

​e) What is the probability that the sample proportion is greater than

0.440.44​?

______

​(Round to three decimal places as​ needed.)

Sandhill Machinery Corporation, a private company following ASPE sold manufacturing equipment for $2,100 each. Each machine carried with it a 2-year warranty against manufacturing defects. From experience, Sandhill Machinery Corporation determined that each machine sold would average $253 in replacement parts. In 2020, the company sold 1,000 machines. Also in 2020, the company incurred $125,000 in total repair costs (the cost of replacement parts from inventory). Sandhill Machinery Corporation also sold an extended warranty for its machines. For $430, customers could purchase an extended warranty that extended the warranty on the machine for an additional 2 years. 800 of the customers that bought machines also purchased the extended warranty. Assume the revenue is earned evenly over the two-year contract. Using the Revenue Approach, prepare the journal entry to record the sale of the machines and extended warranties. (Ignore any cost of goods sold entry).Using the Revenue Approach, prepare the journal entry to record the warranty costs incurred during 2020.

Using the Revenue Approach, prepare the journal entry to record the year-end adjusting entries at December 31, 2020,for the assurance-type warranties assuming Sandhill’s year-end is December 31. Using the Revenue Approach, prepare the journal entry to record the year-end adjusting entries at December 31, 2022 for the service-type warranties. (Note: assume that the cost of repairs has already been recorded during 2022 and prepare any other adjusting entry needed). (

Rundell Corporation uses customers served as its measure of activity. The following report compares the planning budget to the actual operating results for the month of July. Wages and Supplies are purely variable costs while Insurance is all fixed cost. Miscellaneous expense is a mixed cost with $2,500 being the fixed component of the total amount planned.

Comparison of Actual Results to Planning Budget

For the Month Ended July 31

Required: Using the Planning budget column and the assumptions above, determine the unit variable costs and the fixed costs needed to build the Flexible Budget then complete the Revenue and Spending Variances and the Activity Variances for each revenue and expense account and the appropriate totals. You may prepare the Flexible Budget amounts on a separate worksheet and submit, but it is not required.Round answers to whole amounts, use commas if necessary and no dollar signs.

#1        Problem 25 [page 583-584].

The price drivers pay for gasoline often varies a great deal across regions throughout the United States.  The following data show the price per gallon for regular gasoline for a random sample of gasoline service stations for three major brands of gasoline (Shell, BP, and Marathon) located in 11 metropolitan areas across the upper Midwest region (OhioGasPrices.com website, March 18, 2012).

Use a= 0.05 to test for any significant difference in the mean price of gasoline for the three brands.

#2        Information regarding the ACT scores of samples of students in four different majors are given below.

At a 5% level of significance, test to determine whether there is a significant difference in the means of the four populations.

#3        Employees of MNM Corporation are about to undergo a retraining program. Management is trying to determine which of three programs is the best. They believe that the effectiveness of the programs may be influenced by gender. A factorial experiment was designed. You are given the following information.

Test to determine whether there is a significant difference in the means due to program type and gender, and whether significant interaction exists. Use 10% level of significance.

Suppose that the government of China decided to impose a per unit tax on the suppliers of salt.

a. Using a supply and demand model, show and explain the impact that the per-unit tax had on the equilibrium price and quantity of salt.

b. Using the diagram created for your answer to (a), show and explain what effect the per unit tax had on consumer surplus, producer surplus and deadweight loss.

c. List three reasons a government may impose a tax. Discuss the link between government revenue from taxation and elasticity of demand.

The following sample data reflect shipments received by a large firm from three different vendors and the quality of those shipments. (You may find it useful to reference the appropriate table: chi-square table or F table)

Firm : Starbucks

Analyze three actions taken by the firm that affect the objective of sustainability?At least one of these actions should relate to environmental sustainability and at least one should relate to social responsibility. For each action, explain how it affects the environment and/or society, and how those impacts contribute to or detract from the objective of sustainability. Then interpret each action’s impact on the firm’s profits. Is it a profit-maximizing action? Does it negatively impact the firm’s profits? Explain and, where possible, use the tools and ideas that we have developed in class to back up your discussion.

*Write about two to three paragraphs answering the questions above.
