The SourdoughSourdough Bread Company bakes baguettes for distribution to upscale grocery stores. The company has two direct-cost categories: direct materials and direct manufacturing labor. Variable manufacturing overhead is allocated to products on the basis of standard direct manufacturing labor-hours. Following is some budget data for the Sourdough Sourdough
Bread Company:

Direct manufacturing labor use 0.02 hours per baguette
Variable manufacturing overhead $10.00 per direct manufacturing labor-hour

The Sourdough Bread Company provides the following additional data for the year ended December 31, 2017:

Planned (budgeted) output 3,100,000 baguettes

Actual production 2,600,000 baguettes

Direct manufacturing labor 46,800 hours

Actual variable manufacturing overhead $617,760

a. What is the denominator level used for allocating variable manufacturing` overhead? (That is, for how many direct manufacturing labor-hours is Sourdough Bread budgeting?)
b. Prepare a variance analysis of variable manufacturing overhead.
c. Discuss the variances you have calculated and give possible explanations for them.

Rate of return, standard deviation, coefficient of variation personal finance problem mike is searching for a stock to include in his current stock portfolio. he is interested in hi-tech inc.; he has been impressed with the company's computer products and believes hi-tech is an innovative market player. however, mike realizes that any time you consider a technology stock, risk is a major concern. the rule he follows is to include only securities with a coefficient of variation of returns below 1.07. mike has obtained the following price information for the period 2015 through 2018:hi-tech stock, being growth-oriented, did not pay any dividends during these 4 years. a. calculate the rate of return for each year, 2015 through 2018, for hi-tech stock. b. assume that each year's return is equally probable and calculate the average return over this time period. c. calculate the standard deviation of returns over the past 4 years. (hint: treat this data as a sample.) d. based on b and c determine the coefficient of variation of returns for the security. e. given the calculation in d what should be mike's decision regarding the inclusion of hi-tech stock in his portfolio?
