hypothesis tests

you have three movies with ratings from trusted peers:
movie #1: median=5 units
mean=4.35 units
standard deviation=0.76 units

movie #2: median=2 units
mean=2.2 units
standard deviation=0.59 units

movie #3: median=5units
mean=4.5 units
standard deviation=0.62 units

Which statistical test would be the best to use to compare the three rating distributions and see what movie is rated the best, comparing each movie two at a time for a total of three times? (comparing movies 1 & 2, 1 & 3, and 2&3)

The mass of a meteor with a radius of 1 km is about 9 x 1012 kg. The mass of a meteor also is proportional to the cube of its radius. Suppose a meteor with a radius of 8.8 km is moving at 1.7 x 104 m/s when it collides inelastically with the Earth. The Earth has a mass of 5.97 x 1024 kg and assume the Earth is stationary. The kinetic energy lost by the asteroid in this collision will be transferred to non-conservative work in heating the atmosphere and physically destroying the place where it lands. The Tsar Bomb, the largest atomic bomb ever tested, released 2.1 x 1017 J of energy. (Which, by the way, is 1000's of times more energy compared to the atomic bombs dropped in World War II.) How many MILLIONS of equivalent Tsar Bombs is the kinetic energy lost of this meteor?

Mathews Company manufactures only one product. For the year ended December 31, the contribution margin increased by$16,224 from the planned level of $545,376. The president of Mathews Company has expressed some concern about this increase and has requested a follow-up report. The following data have been gathered from the accounting records for the year ended December 31:  Actual Planned Difference—Increase (Decrease) Sales$1,071,200 $1,055,184$16,016 Variable costs: Variable cost of goods sold $405,600$426,816 $(21,216) Variable selling and administrative expenses 104,000 82,992 21,008 Total variable costs$509,600 $509,808$(208) Contribution margin $561,600$545,376 $16,224 Number of units sold 10,400 11,856 Per unit: Sales price$103 $89 Variable cost of goods sold 39 36 Variable selling and administrative expenses 10 7 Required: 1.

2. At a meeting of the board of directors on January 30, the president, after reviewing the contribution margin analysis report, made the following comment:

It looks as if the price increase of $14 was a favorable tradeoff for decreased sales volume, yet variable cost of goods sold was less than planned and variable selling and administrative expenses were out of control and needed to be investigated. He went on to say that since the favorable tradeoff between higher price and lower sales volume was so successful, the company should consider increasing the sales price to$130.

Do you agree or disagree with the president's proposal and which reason would best explain your decision about the data?

Disagree with the president because the majority of the decrease in the variable cost of goods sold was due to the variable cost quantity factor and the increased variable selling and administrative expenses are probably a result of additional selling efforts needed to be competitive at higher prices.

Agree with the president because the unit cost factor for the variable selling and administrative cost is greater than the unit cost factor for the variable cost of goods sold, making an investigation necessary.

Agree with the president because the total effect of change in sales is greater than the total effect of changes in variable cost of goods sold, making an additional price raise attractive for more profits.

Disagree with the president because the contribution margin as a percentage of sales is greater for the planned sales level than the actual sales level, making his concern about variable selling and administrative expenses unwarranted.

Agree with the president because the majority of the decrease in the variable cost of goods sold was due to the sales price factor, as well as an increase in the variable selling and administrative expenses as a percentage of sales, making an additional price raise attractive for more profits.

1. Import Scanner class and create scanner object to read user input. Write a program to read input from keyboard for the first item with following: 2. Input name of the first item purchased and save it to local variable “article1”. 3. Input quantity purchased and save it to a local variable “quantity1”. 4. Input unit price and save it to a local variable “unit_cost1”. Write a program to read input from keyboard for the second item with following: 5. Input name of the second item purchased and save it to a local variable “article2”. 6. Input quantity purchased and save it to a local variable “quantity2”. 7. Input unit price and save it to a local variable “unit_cost2”. 8. Input amount of cash received from a client and save it to a local variable “cash”. Calculate amounts for sales receipts 9. Calculate the amount of the first item by multiplying quantity and unit cost, and save it to a local variable “price1”. 10. Calculate the amount of the second item by multiplying quantity and unit cost, and save it to a local variable “price2”. 11. Calculate the sum amount of items purchased, and save it to a local variable “sub_total”. 12. Calculate the sales tax of items purchased, and save it to a local variable “tax”. 13.

Referring to Table 14-3, when the economist used a simple linear regression model with consumption as the dependent variable and GDP as the independent variable, he obtained an r2 value of 0.971. What additional percentage of the total variation of consumption has been explained by including aggregate prices in the multiple regression? In other words, the economist was explaining 97.1%, how much has that percentage or R-square increased after adding "price" as a second independent variable?
