The manufacturer of a new racecar engine claims that the proportion of engine failures due to overheating for this new engine, (p1)(p1), will be no higher than the proportion of engine failures due to overheating of the old engines, (p2)(p2). To test this statement, NASCAR took a random sample of 215215 of the new racecar engines and 200200 of the old engines. They found that 1818 of the new racecar engines and 88 of the old engines failed due to overheating during the test. Does NASCAR have enough evidence to reject the manufacturer's claim about the new racecar engine? Use a significance level of α=0.1α=0.1 for the test.

Step 4 of 6 :

Conclusion.

1. Crazy Cliff’s Car Coral crushes competition causing college customers considerable consternation. Crazy Cliff’s has no debt and considering opening a new dealership – Crazier Cliff’s. Crazy Cliff requires that all new projects have a return on equity of 18%. The new dealership is expected to increase net income by $200,000 per year over the projects 10-year life. The new dealership will be placed on land Crazy Cliff purchased for $400,000 2 years ago; the land could be sold today for $450,000. Crazy Cliff plans on operating the dealership out of a brand-new double-wide that can be purchased for $80,000 and will be depreciated to zero over 10 years. The double-wide has no salvage value and the land is expected to be sold for $500,000. Assume a tax rate of 25%. What are the IRR and payback period of the project? Should the project be accepted?

Johnson Electronics is considering extending trade credit to some customers previously considered poor risks. Sales would increase by $190,000 if credit were extended to these new customers. Of the new accounts receivable generated, 7 percent will prove to be uncollectible. Additional collection costs will be 5 percent of sales, and production and selling costs will be 78 percent of sales. The firm is in the 30 percent tax bracket.

a. Compute the incremental income after taxes.

b. What will Johnson’s incremental return on sales be if these new credit customers are accepted? (Input your answer as a percent rounded to 2 decimal places.)

c. If the accounts receivable turnover ratio is 5 to 1, and no other asset buildup is needed to serve the new customers, what will Johnson’s incremental return on new average investment be? (Do not round intermediate calculations. Input your answer as a percent rounded to 2 decimal places.)

Suppose we are thinking about replacing an old computer with a new one. The old one cost us $1,700,000; the new one will cost, $2,053,000. The new machine will be depreciated straight-line to zero over its five-year life. It will probably be worth about $465,000 after five years. The old computer is being depreciated at a rate of $368,000 per year. It will be completely written off in three years. If we don’t replace it now, we will have to replace it in two years. We can sell it now for $567,000; in two years, it will probably be worth $165,000. The new machine will save us $383,000 per year in operating costs. The tax rate is 22 percent, and the discount rate is 11 percent.

a-1. Calculate the EAC for the the old computer and the new computer.

a-2. What is the NPV of the decision to replace the computer now?

QUESTION

The table below shows data collected over a two-hundred-year time span in a woodland area. Each year, the number of new invasive species that appeared for the very first time in that woodland was recorded. Do new invasive species appear in random years, or non-random years? If they appear randomly, the data should follow a Poisson distribution.

1. Calculate the mean number of new invasive species per year
2. Test whether the data fit a Poisson distribution, making sure the data meet the assumptions of a Chi-square goodness-of-fit test.

The management of Ballard MicroBrew is considering the purchase of an automated bottling machine for $62,000. The machine would replace an old piece of equipment that costs $16,000 per year to operate. The new machine would cost $7,000 per year to operate. The old machine currently in use is fully depreciated and could be sold now for a salvage value of $23,000. The new machine would have a useful life of 10 years with no salvage value. Required: 1. What is the annual depreciation expense associated with the new bottling machine? 2. What is the annual incremental net operating income provided by the new bottling machine? 3. What is the amount of the initial investment associated with this project that should be used for calculating the simple rate of return? 4. What is the simple rate of return on the new bottling machine? (Round your answer to 1 decimal place i.e. 0.123 should be considered as 12.3%.)

Write Program in C:

Write a program that: program starts; declares and initializes to 7.25% constant float variable NJSALES_TAX; declares and initializes to 1000 an integer variable total; declares and initializes to zero a float variable grand_total; prompt and input on new line total; calculate grand_total to equal total plus (total*NJSALES_TAX); if grand_total <= 1000 print on new line “Grand total is less than or equal to 1000 it is $” and the grand_total to two decimal places; else if grand_total between 1000 <= 2000 print on new line “Grand total is more than 1000 less than or equal to 2000 it is $” and the grand_total to two decimal places; else print on new line “Grand total is greater than 2000 it is $” and the grand_total to two decimal places; just before ending print on new line “Program finished!” then terminate program.

suppose we are thinking about replacing an old computer with a new one. the old one cost $1,800.000; the new one will cost, $2183.000. the new machine will be depreciated straigth line to zero over its five year life. it will probably be worth about $540.000 after five years. the old computer is being depreciated at a rate of $408.000 per year. it will be completely written off in three years. if we dont replace it now, we will have to replace it in two years. we can sell it now for 612000; in two years it will probably be worth $180000. the new machine will save us $359000 per year in operating costs. the tax rate is 22 percent and the discount rate is 9 percent. a. calculate the EAC for the old computer and the new computer. a2. what is the NPV of the decision to replace the computer now?

A clinical trial is conducted comparing a new pain reliever for arthritis to a placebo. Participants are randomly assigned to receive the new treatment or a placebo and the outcome is pain relief within 30 minutes. The data are shown here.

Is there a significant difference in the proportions of

patients reporting pain relief?

Run the test at a 5% level of significance.

H0: p1= p2(equivalent to RD = 0, RR=1 or OR=1)

Can they reject the H_0?

Group of answer choices

Yes, Reject H0, there is a statistically significant difference in the proportions of patients reporting pain relief in the new medication and placebo groups

No, Fail to Reject H0, there is no statistically significant difference in the proportions of patients reporting pain relief between the new medication and placebo groups
