The table below lists the frequency of wins for different post positions in the Kentucky Derby horse race.

Use a 0.05 significance level to test the claim that the likelihood of winning is the same for the different post positions.

What is the critical value (the X2 value)? [Round to the nearest thousandths place]

A manager at another store wants to know if an add campaign increased her average monthly revenue above $100 (thousand). She has provided you 36 months of data. She wants to know at the 95% condence level and at the 99% confidence level. She will be even more impressed if you can give the exact p-value and accurately describe what it means. Show how you solved this problem then explain what you did in words in the text box below. For example, is this a two-sided or one sided test? How did you proceed from there? You should label some of the cells with words then put the value next to those words. Heres the data: Month Revenue (thousands) 1 102.87 2 107.28 3 100.78 4 96.50 5 97.51 6 98.26 7 104.88 8 103.95 9 107.00 10 106.98 11 106.01 12 101.70 13 98.78 14 98.92 15 99.08 16 102.45 17 95.93 18 101.46 19 105.57 20 103.24 21 100.59 22 104.20 23 99.83 24 105.93 25 102.85 26 102.55 27 104.91 28 106.13 29 95.92 30 97.51 31 107.28 32 95.69 33 99.50 34 95.76 35 95.62 36 101.17

The Foundational 15 [LO2-1, LO2-2, LO2-3, LO2-4]

[The following information applies to the questions displayed below.]

Sweeten Company had no jobs in progress at the beginning of March and no beginning inventories. The company has two manufacturing departments--Molding and Fabrication. It started, completed, and sold only two jobs during March—Job P and Job Q. The following additional information is available for the company as a whole and for Jobs P and Q (all data and questions relate to the month of March):

Sweeten Company had no underapplied or overapplied manufacturing overhead costs during the month.

Required:

For questions 1-8, assume that Sweeten Company uses a plantwide predetermined overhead rate with machine-hours as the allocation base. For questions 9-15, assume that the company uses departmental predetermined overhead rates with machine-hours as the allocation base in both departments.

Foundational 2-15

Answer the question below, i post this question for fourth time please answer it
contains a list of available investment projects and their respective cash flows. Using a cost of capital of 10%,

1. Find the payback period, net present value and internal rate of return for each project.
2. Based on the results, identify conflicts in ranking the above projects based on the IRR and NPV approaches, i.e. a project that has a higher rank using IRR but a lower rank using NPV and vice versa. You should also provide a discussion of what caused the conflict
3. Provide a discussion of the advantages and disadvantages of all the capital budgeting techniques covered in this course, and identify methods to overcome the disadvantages (if available)
4. Provide a brief discussion (a small paragraph) of the practicality (uses in real life) of the different capital budgeting methods.

Problem 15-01 (Algorithmic)

Consider the following time series data.

Using the naïve method (most recent value) as the forecast for the next week, compute the following measures of forecast accuracy.

1. Mean absolute error. Round your answer to one decimal place.
   
   
   
2. Mean squared error. Round your answer to one decimal place.
   
   
   
3. Mean absolute percentage error. Round your answer to two decimal places.
   
   
   
4. What is the forecast for week 7? Round your answer to the nearest whole number.

1. Construct a confidence interval to estimate the mean height and the mean weight.

a. find the sample mean and the sample standard deviation of the height

b. find the sample mean and the sample deviation of the weight

c. construct a confidence interval to estimate the mean height.

d. construct a confidence interval to estimate the mean weight.

2. Test a claim that the mean height of people you know is not equal to 64 inches using the p-value method or the traditional method.

a. state the Ho and the h1.

b. Find the p value or critical value(s)

c. Draw a conclusion

3. Find the correlation coefficient between and the height and the weight. Construct the equation of the regression line and use it to predict the weight of a person who is 68 inches tall.

1. In which of the following ranges you can find the Upper Control Limit of the control chart?
   1. 0.1427
   2. 0.1536
   3. 0.1677
   4. Not computable with information available
2. In which of the following ranges you can find the Lower Control Limit of the control chart?
   1. Does not exit (or 0) to under 0.0030
   2. 0.0030 to under 0.0040
   3. 0.0040 to under 0.05
   4. Above 0.05
3. Investigation of the above data shows that:
   1. Absenteeism is not a problem, it is in state of statistical control  
   2. Absenteeism is out of statistical control because you found one day out of the control limits
   3. Absenteeism is out of statistical control because you found two days out of the control limits
   4. Absenteeism is out of statistical control because you found three days out of the control limits
