I want you guys to rewrite this lab procedure, and it is fine if it was shorter than this.

An air track was fitted with two photocell bridges, one on each side of the collision region. Each bridge was operating in a gate mode timer that allows the collection of time intervals before and after collision. To ensure that friction and gravity have minimal effects, the track was leveled. Before starting the experiment, we ensured that loss in velocity was no greater than two percent in either direction. To check this, we sent one glider in one direction and noted the time to cross each photocell placed one meter apart. The difference between the two times divided by the time to cross the first photocell was the fraction of momentum that was lost due to friction and gained or lost due to gravity. The track was readjusted accordingly and the check was repeated in the other direction.

The first step in starting the experiment was measuring the masses of the two gliders (i.e. the heavy glider and the light glider). The masses of the gliders were made “heavy” or “light” by adding trimming weights. Then, a series of four collisions (each repeated three times) were conducted

“H” indicates heavy glider, “L” indicates light glider, “Off” indicates that the collision was made elastic by facing the bumpers toward one another, and “On” indicates that the collision was made inelastic by the mounting the “sticky bumpers” on each end (i.e. pin and putty attachments).

Using the memory mode of the photoelectric timers, we were able to collect times for both instances (before and after collision) that that glider past the photobridges. The first data point was our first time point and the second data point was the total of the first and second time point. Therefore, to get the second time, we had to subtract the first time point from the second data point. These times were then used to caluculate the velocities and subsequently the momentum and kinetic energy of both gliders.

An expert who works for a car magazine obtained random data (rounded to the nearest thousand) among two categories of used or new cars:

Domestic
Foreign

The expert would like to understand sales based on list price (rounded to the nearest thousand dollars), sale price (rounded to the nearest thousand dollars), and number of days it takes to sell each car. The complete data set is in the file named Cars.

Managerial Report

Prepare a report (see below) that summarizes your assessment of the nature of the car market. Be sure to include the following seven items in your report.

1 Descriptive statistics (mean, median, range, standard deviation, and coefficient of variation) to summarize each of the three variables for the all Domestic cars. Use z-scores to determine if there any outliers in the data set for any of the three variables. If there are any outliers in any category, please list them and state for which category they are an outlier. If a result is an outlier, state whether it is below or above the mean.

2 Descriptive statistics (mean, median, range, standard deviation, and coefficient of variation) to summarize each of the three variables for the all Foreign cars. Use z-scores to determine if there any outliers in the data set for any of the three variables. If there are any outliers in any category, please list them and state for which category they are an outlier. If a result is an outlier, state whether it is below or above the mean.

3 Compare your summary results from #1 and #2. Discuss any specific statistical results that would help the car expert understand the car market.

4 Develop a 98% confidence interval estimate of the population mean sales price and population mean number of days to sell for Domestic cars. What is the Margin of error? What are the lower (or left) and upper (or right) endpoints of the confidence interval? Interpret your results.

5 Develop a 98% confidence interval estimate of the population mean sales price and population mean number of days to sell for Foreign cars. What is the Margin of error? What are the lower (or left) and upper (or right) endpoints of the confidence interval? Interpret your results.

6 Assume the car expert requested estimates of the mean number of days to sell for the Domestic cars with a margin of error of seven days and the mean number of days of Foreign cars with a margin of error of eight days. Using 98% confidence, how large should the sample sizes be for each?

7 Suppose a Domestic car has a list price of $30,000 and a Foreign car has a list price of $30,000. What is your estimate of the final selling price (based on the percent difference for the sale and list price) and number of days required to sell each of these cars?

Conn Man’s Shops, a national clothing chain, had sales of $320 million last year. The business has a steady net profit margin of 6 percent and a dividend payout ratio of 25 percent. The balance sheet for the end of last year is shown. Balance Sheet End of Year (in $ millions) Assets Liabilities and Stockholders' Equity Cash $ 22 Accounts payable $ 72 Accounts receivable 27 Accrued expenses 28 Inventory 76 Other payables 44 Plant and equipment 115 Common stock 44 Retained earnings 52 Total assets $ 240 Total liabilities and stockholders' equity $ 240 The firm's marketing staff has told the president that in the coming year there will be a large increase in the demand for overcoats and wool slacks. A sales increase of 20 percent is forecast for the company. All balance sheet items are expected to maintain the same percent-of-sales relationships as last year,* except for common stock and retained earnings. No change is scheduled in the number of common stock shares outstanding, and retained earnings will change as dictated by the profits and dividend policy of the firm. (Remember, the net profit margin is 6 percent.) *This includes fixed assets, since the firm is at full capacity. a. Will external financing be required for the company during the coming year? Yes No b. What would be the need for external financing if the net profit margin went up to 7.50 percent and the dividend payout ratio was increased to 50 percent?
