The mean preparation fee H&R Block charged retail customers last year was $183 (the Wall Street Journal, March 7, 2012). Use this price as the population mean and assume the population standard deviation of preparation fees is $50.

1. What is the probability that the mean price for a sample of 30 H&R Block retail

   customers is within $8 of the population mean?

2. What is the probability that the mean price for a sample of 50 H&R Block retail

   customers is within $8 of the population mean?

3. What is the probability that the mean price for a sample of 100 H&R Block retail

   customers is within $8 of the population mean?

4. Which, if any, of the sample sizes in parts (a), (b), and (c) would you recommend to

   have at least a .95 probability that the sample mean is within $8 of the population mean?

i need DISTRIBUTION, MEAN, STANDARD DEVIATION, of x-bar for each question 1-3 and  175<xbar<191 please.

A researcher is interested in whether the phonics method of teaching reading is more or less effective than the sight method, depending on what grade the child is in. Twenty children were randomly selected from each of three grades: kindergarten (K), first grade (1), and second grade. Achievement was measured in terms of reading comprehension where higher scores indicate better comprehension. Within each grade, 10 children were assigned to each of two methods of teaching reading - phonics or sight. The data are as follows:

                        Grade Levels

                        K         1          2                                              K         1                2

                        14        25        49                                            17        35            34

                        16        27        46                                            19        40            34

1. State the Null hypotheses for each main effect and interaction – 5 points
2. Present the means and SD for each level of each factor– 5 points.
3. Test the null hypothesis for both main effects and interactions and present the ANOVA source table with all relevant statistics– 15 points.

4. Specify all variables– 5 points.
5. Compute, report and explain results from the HSD post hoc follow-up test– 10 points..
6. Present a graph of the interaction of the two factors– 5 points.
7. Write a statement as to your conclusions– 5 points..

Note. This is a Two-Way ANOVA (i.e., 2 IVs). One IV has two levels and one IV has three levels. Thus, a 2 X 3 ANOVA that will produce 6 cell means, 2 row means and 3 column means.

Consumer Research, Inc., is an independent agency that conducts research on consumer attitudes and behaviors for a variety of firms. In one study, a client asked for an investigation of consumer characteristics that can be used to predict the amount charged by credit card users. Data were collected on annual income, household size, and annual credit card charges for a sample of 50 consumers and is shown below:

1. Develop two simple regression equations
   1. Use annual income as the independent variable and annual credit card charges as the dependent variable
   2. Use household size as the independent variable and annual credit card charges as the dependent variable

1. • Which variable is the better predictor of annual credit card charges?
   • Discuss your findings.
2. Develop an estimated regression equation for annual credit card charges with annual income and household size as the independent variables.
   • Discuss your findings.
   • What is the predicted annual credit card charge for a three-person household withan annual income of $40,000?
3. Would the inclusion of additional independent variables improve the model? Why? If so, what additional variables would you include?

flipping a coin 5 times, with 95 percent chance of being head and 5 percent chance of being tail and you win 20 dollars for each head, and loses 20 dollars for each tail. 1)What is the probability of getting one head? 2) two heads? 3) three heads?4) four heads? 5) five heads? 6)What is the probability of getting at least one head? 7) at least two heads?8) at least three heads? 9) at least four heads? 10) find the expected value for question 1,2 and 3.

One hundred blood samples were taken from 100 individuals. All of the blood samples were run through two machines to determine if the machines were testing samples appropriately. We expect that both machines should yield similar results. Below are the results of the analysis. Assume there are 100 sample and they are normal. Are the two machines similar? Should we check into whether one machine should be replaced? Show all of your work.

Arndt, Inc., reported the following for 2018 and 2019 ($ in millions):
PLEASE FILL IN THE BLANKS

1. Expenses each year include $40 million from a two-year casualty insurance policy purchased in 2018 for $80 million. The cost is tax deductible in 2018.
2. Expenses include $3 million insurance premiums each year for life insurance on key executives.
3. Arndt sells one-year subscriptions to a weekly journal. Subscription sales collected and taxable in 2018 and 2019 were $38 million and $67 million, respectively. Subscriptions included in 2018 and 2019 financial reporting revenues were $35 million ($13 million collected in 2017 but not recognized as revenue until 2018) and $43 million, respectively. Hint: View this as two temporary differences—one reversing in 2018; one originating in 2018.
4. 2018 expenses included a $29 million unrealized loss from reducing investments (classified as trading securities) to fair value. The investments were sold in 2019.
5. During 2017, accounting income included an estimated loss of $7 million from having accrued a loss contingency. The loss was paid in 2018 at which time it is tax deductible.
6. At January 1, 2018, Arndt had a deferred tax asset of $8 million and no deferred tax liability.

2. Prepare a schedule that reconciles the difference between pretax accounting income and taxable income. Using the schedule, prepare the necessary journal entry to record income taxes for 2018.

Prepare a schedule that reconciles the difference between pretax accounting income and taxable income. (Amounts to be deducted should be indicated with a minus sign. Enter your answers in millions (i.e., 10,000,000 should be entered as 10).)

Hayden Inc. has a number of copiers that were bought four years ago for $21,000. Currently maintenance costs $2,100 a year, but the maintenance agreement expires at the end of two years and thereafter the annual maintenance charge will rise to $8,100. The machines have a current resale value of $8,100, but at the end of year 2 their value will have fallen to $3,600. By the end of year 6 the machines will be valueless and would be scrapped.

Hayden is considering replacing the copiers with new machines that would do essentially the same job. These machines cost $26,000, and the company can take out an eight-year maintenance contract for $1,300 a year. The machines will have no value by the end of the eight years and will be scrapped.

Both machines are depreciated by using seven-year MACRS, and the tax rate is 40%. Assume for simplicity that the inflation rate is zero. The real cost of capital is 8%.

a. Calculate the equivalent annual cost, if the copiers are: (i) replaced now, (ii) replaced two years from now, or (iii) replaced six years from now. (Do not round intermediate calculations. Enter your answers as a positive value rounded to 2 decimal places.)
