A genetic experiment with peas resulted in one sample of offspring that consisted of 404 green peas and 154 yellow peas.

a. Construct a 95​% confidence interval to estimate of the percentage of yellow peas.

b. It was expected that​ 25% of the offspring peas would be yellow. Given that the percentage of offspring yellow peas is not​ 25%, do the results contradict​ expectations?

A publisher reports that 42% of their readers own a particular make of car. A marketing executive wants to test the claim that the percentage is actually different from the reported percentage. A random sample of 250 found that 35% of the readers owned a particular make of car. Find the value of the test statistic. Round your answer to two decimal places.

Decision Making – Equipment Replacement

Mathews manages an assembly facility of Orthom Scientific. A supplier approaches Mathews about replacing a large piece of manufacturing equipment that Orthom uses in its process with a more efficient model. While the supplier made some compelling arguments in favor of replacing the 3-year-old equipment, Mathews is hesitant. Mathews is hoping to be promoted next year to manager of the larger plant near Orthom’s headquarters, and he knows that the accrual-basis net operating income of the assembly plant he manages will be evaluated closely as part of the promotion decision. The following information is available concerning the equipment replacement decision:

The historic cost of the old machine is $600,000. It has a current book value of $240,000, two remaining years of useful life, and a market value of $144,000. Annual depreciation expense is $120,000. It is expected to have a salvage value of $0 at the end of its useful life.
The new equipment will cost $360,000. It will have a 2-year useful life and a $0 salvage value. Orthom uses straight-line depreciation on all equipment.
The new equipment will reduce electricity costs by $70,000 per year and will reduce direct manufacturing labor costs by $60,000 per year.

For simplicity, ignore income taxes and the time value of money.

Required:

Assume that Mathews’ priority is to receive the promotion and he makes the equipment replacement decision based on next year’s accrual-based net operating income. Which alternative would he choose? Show your calculations.
What are the relevant factors in the decision? Which alternative is in the best interest of the company over the next 2 years? Show your calculations.
At what cost would Mathews be willing to purchase the new equipment? Explain.
