A study of reading comprehension in children compared three methods of instruction. The three methods of instruction are called Basal, DRTA, and Strategies. As is common in such studies, several pretest variables were measured before any instruction was given. One purpose of the pretest was to see if the three groups of children were similar in their comprehension skills. The READING data set described in the Data Appendix gives two pretest measures that were used in this study. Use one-way ANOVA to analyze these data and write a summary of your results.

Leila runs a lawn mowing/maintenance service for busy
homeowners. She has six potential customers and each is has a
different maximum price they are willing to pay per week. The
customers and the maximum price each is willing to pay each week is
as follows:
Customer Price
Lorraine $40
Gilda

Java program. The Spacely Sprocket company has expanded operations and is now producing 50 different kinds of sprockets. The different sprockets are numbered 1 though 50. During the month of November, orders have been taken for the different sprockets. The following input file contains records where each record contains a sprocket number (1-50) followed by the quantity ordered: November Orders.txt (this will be at the bottom)
Using the below input file of orders, rewrite the Spacely Sprocket program to produce a summary report for all 50 sprockets produced. Rather than using 50 separate accumulator variables, you must use a single array to represent the 50 different accumulators. Use the array and loops in your program to summarize the orders and output the report. Don't forget to initialize each of the array locations to 0 (because they are accumulators). For full credit, be sure to display the report in a Scrolling Pane in a Window.

Donald has recently lost his job as the President of a large North American country and has returned to the family hotel business. Their most prestigious hotel Tramp Tavern has been closed for two years whilst it has undergone refurbishment and the hotel is about to be relaunched. The hotel runs conventionally and has a number of cost centres such as Reception, Concierge, Repairs and Maintenance which are relatively fixed. The hotel also has variable costs relating to cleaning and servicing rooms. You have been provided with the following data regarding the re-furbished Tramp Tavern: Available Rooms 400 Average Room Tariff (per night) $230 Fixed Financing Costs $10 million Fixed Operating Costs $15 million Variable Operating Costs (per night when occupied) $50 Required a) What is the breakeven point (in total room rentals for the year) for the Tramp Tavern? Show the percentage of occupancy that the hotel must achieve in order to break even (show all calculations)

A Firm studied the number of lost-time accidents occurring at its plant. Past records show that 7% of the employees suffered lost-time accidents last year. Management assumes that a special safety program will reduce these accidents to 6% in the current year. Also, it estimates that 15% of the employees who had such accidents in the last year will face a lost-time accident in the current year.
a. What is the probability an employee will experience a lost-time accident in both years (to 2 decimals)?
b. What is the probability an employee will experience a lost-time accident over the two-year period (to 2 decimals)

There are seven photocopiers, and three of these photocopiers are defective. The buyer begins to test them one at a time to figure out which three are defective.
e. Given that exactly one of the defective photocopiers was found within the first three tests, what is the probability that the other two defective photocopiers are found within the next three tests?
f. Given that exactly two of the defective photocopiers were found within the first three tests, what is the probability the last defective photocopier is found within the next two tests?
g. Given that exactly two of the defective photocopiers were found within the tests 1, 3, 5, what is the probability the other defective photocopier was found on tests 6 or 7?
h. Given the last defective photocopier was found within the last two tests, what is the probability that the first two defective photocopiers were found within the first three tests?

Monica’s cousin, Chloe, would like to set up a small candy boutique at school for Valentine’s Day next February (this family has a lot of entrepreneurs!!). She has decided that demand will be for 10 boxes, 20 boxes or 30 boxes. Each box costs her $12 but she thinks she can sell each one for $15. If she overstocks, then she can get a salvage value of $8 per box from the local candy shop. If she runs out of candy while there is still demand, she will suffer a lost goodwill charge of $4 per box. Show the conditional payoffs facing her in the chart below.
1) Fill out the table
2) Which decision should Chloe make if she is an optimist? Explain.
3) Which decision should Chloe make if she is a pessimist? Explain.
4) Suppose that a friend offers Chloe additional information regarding demand but is charging $50 for it. Should Chloe pay for this information? Why or why not? Show all work.

Problem 17-5A Parts 1, 2 & 3
Required:
1. Using a plantwide overhead rate based on cases,
compute the overhead cost that is assigned to each case of Extra
Fine Salsa and each case of Family Style Salsa.
2. Using the plantwide overhead rate, determine
the total cost per case for the two products if the direct
materials and direct labor cost is $10 per case of Extra Fine and
$8 per case of Family Style.
3.a. If the market price of Extra Fine Salsa is
$18 per case and the market price of Family Style Salsa is $13 per
case, determine the gross profit per case for each product.
3.b. What might management conclude about the
Family Style Salsa product line?
5. If the market price is $18 per case of Extra Fine and $13 per case of Family Style, determine the gross profit per case for each product. (Round your intermediate calculations and final answers to 2 decimal places.)
***please be advised, there is NO PART 4 to this question. It goes from 3b, to 5.
