c) Draw a histogram of the horsepower data.

d) Using the actual data, find the number of cars with horsepower higher than the first car listed (211 hp). Then divide by 15 to get a percent

e) Using normalcdf, find the percent of cars with more horsepower than the first car listed (211 hp).

f) Compare your results of parts d and e. Are they close?

g) Do the data appear normal? Explain using parts b ,e and f

please answer only e, f, and g questions  !! thanks

here is A to D answers

Answers B

A) If the observations are

X1,X2,X3,X4,X5…………X15

Mean= 219.3

Std=72.9

B) A normal probability plot is created using Minitab

C) The Histogram of the horsepower data is created using Minitab

X represent horsepower

D) Number of cars with horsepower higher than first car listed(2011hp)=6

Percent=6/15*100=40%

Patti Devine owns Devine Decorating. One of her most popular items is the Remind-a-Chime digital clock. This programmable clock issues "voice-based" reminders of important events like birthdays, anniversaries, etc. Following is the Remind-a-Chime inventory activity for January. The clocks on hand at January 1 had a unit cost of $140.

(a) If Devine uses the first-in, first-out (FIFO) inventory method (periodic approach), what values would be assigned to ending inventory and cost of goods sold? How much is gross profit? (b) If Devine uses the last-in, first-out (LIFO) inventory method (periodic approach), what values would be assigned to ending inventory and cost of goods sold? How much is gross profit? (c) If Devine uses the weighted-average inventory method (periodic approach), what values would be assigned to ending inventory and cost of goods sold? How much is gros

Susan Smith, president of Miami Co., recently read an article that claimed that at least 100 of the country's largest 500 companies were either adopting or considering adopting the last-in, first-out (LIFO) method for valuing inventories. The article stated that the firms were switching to LIFO to (1) neutralize the effect of inflation in their financial statements, (2) eliminate inventory profits, and (3) reduce income taxes. Ms. Smith wonders if the change would benefit her company. Miami Co. currently uses the first-in, first-out (FIFO) method of inventory valuation in its periodic inventory system. The company has a high inventory turnover rate, and inventories represent a significant proportion of the assets. Ms. Smith has been told that the LIFO system is more costly to operate and will provide little benefit to companies with high turnover. She intends to use the inventory method that is best for the company in the long run rather than selecting a method just becuase it is the current fad. Your assignment: Explain to Ms. Smith what "inventory profits" are and how the LIFO method of inventory valuation could reduce them. Also explain to her the conditions that must exist for Miami Co. to receive tax benefits from a switch to the LIFO method

Hilton Corporation began operations on 1-1-2012. Hilton used the last-in-first-out (LIFO) inventory costing method from 1-1-2012 through 12-31-2014. Presented below are effects of using LIFO for 2014 and earlier years.

Hilton Corporation changed its inventory costing method from LIFO to the first-in-first-out (FIFO) as of 1-1-2015. Presented below are effects of using FIFO for 2014 and earlier years.

When Hilton issued its 2015 financial statements, it elected to provide comparative statements from the three previous years, i.e., 2012, 2013 and 2014. The change will be accounted for using the retrospective approach.

Required

When the 2015 financial statements are issued in April of 2016, what will be the comparative retained earnings from the 12-31-2013 balance sheet ?

ISYS 350, Assignment 2,

Part 1:

Create a C# Form with a textbox and a button. The box is for a user to enter a number

of seconds. And when the user clicks the button, the program displays the equivalent

number of hours, minutes and seconds using a MessageBox. Show method. If the

seconds entered is less than 60, your program should only display the seconds; if the

seconds is a least 60 and less than 3600, your program should display minutes and

seconds; if the second is at least 3600, your program should display hours, minutes

and seconds.

Use the following data to test your program:

47 seconds: 47 seconds (don’t show 0 hour and 0 minute)

645 seconds: 10 minutes, 45 seconds (don’t show 0 hour)

7565 seconds: 2 hours, 6 minutes, 5 seconds

Requirements:

1. Input validation: The number of seconds cannot exceed 86400. You must use

textbox’s Validating event to do the validation.

2. Turn in the form’s screenshot and the code. (Note: You can use the Alt

+ PrintScrn keys to capture only the active window.)

Part 2: An electric company charges to their customers based on Kilowatt-Hours

(Kwh) used. The rules to compute the charge are:

First 100 Kwh, 35 cents per Kwh

Each of the next 100 Kwh (up to 200 Kwh), 45 cents per Kwh

(the first 100 Kwh used is still charged at 35 cents each)

Each of the next 300 Kwh (up to 500 Kwh) 65 cents per Kwh

All Kwh over 500, 80 cents per KH

Create a C# Form with a textbox to enter Kwh used, a read-only textbox to display the

electricity charges, and a button to compute the charges. The Kwh used could be a

number with decimals.

Requirements:

1. Input validation: Use the KWH textbox validating event to ensure the KWH cannot

exceed 2000. Test your program with (1) Kwh=4500, (2) Kwh = 350

2. Turn in the form’s screenshot and the code

Q1: A firm uses physical capital, which is fixed at 4 units, and labour (L) to make its product. The price of physical capital is $250 per unit and the price of labour is $100 per unit.

a) Complete the following table by filling in the columns for marginal product of labour (MP_L), average product of labour (AP_L), total fixed cost (TFC), total variable cost (TVC), total cost (TC), average fixed cost (AFC), average variable cost (AVC), average total cost (ATC) and marginal cost (MC). Show values to 2 decimal places if they are not whole numbers. Hint: Do not confuse L, the amount of labour used with Q, the amount of output produced.

b) Why does MC increase at some point when the firm’s output increases? Hint: MC is related to MP_L.

c) How does AVC change (increase, decrease or no change) when the firm uses more labour and AP_L increases?

d) Why does AFC decrease when the firm’s output increases?

e) Why does AVC increase at some point when the firm’s output increases? Hint: How will your ECON 1220 mark will affect your GPA?

f) Which costs would change if the price of physical capital increased from $250 per unit to $300 per unit AND how would these costs change (increase or decrease)?

g) Which costs would change if the price of labour increased from $100 per unit $150 per unit AND how would these costs change (increase or decrease)?

1. Over the past 200 stock-trading days data is collected concerning whether the stock index, called the S&P 500, increased or decreased as well as whether the individual stock Apple increased or decreased. Apple stock increased in price on 130 of the days. The S&P 500 increased on 150 of the days. Finally, Apple increased and the S&P 500 increased on 100 of the days. (assume the index either increases or decreases and assume the stock either increases or decreases, ie, neither the stock nor the index ever stays the same from the previous day) What is the probability that on a randomly chosen day that Apple’s stock price decreases or the S&P Index increases? (please round your answer to 4 decimal places)
