OCT 2020 PUTS - last price 7.90 ; vol - ; strike 28.00

1. You sold twenty Oct 2020 put contracts today at $7.90. Two weeks later the stock trades at $22.30 and the premium on the put is $9.90. How much money have you made or lost at this point in time?

2. Briefly explain whether selling uncovered calls is more, less or of equal risk than selling puts?

For each of the questions below, a histogram is described. Indicate in each case whether, in view of the Central Limit Theorem, you can be confident that the histogram would look like approximately a bell-shaped (normal) curve, and give a brief explanation why (one sentence is probably sufficient). There are no data for these questions, so you will not need to use the computer to answer these questions.

A police department records the number of 911 calls made each day of the year, and the 365 values are plotted in a histogram.

The day before an election, fifty different polling organizations each sample 500 people and record the percentage who say they will vote for the Democratic candidate. The 50 values are plotted in a histogram.

The fifty polling organizations also record the average age of the 500 people in their sample, and the 50 averages are plotted in a histogram.

One hundred batteries are tested, and the lifetimes of the batteries are plotted in a histogram.

Two hundred students in a statistics class each flip a coin 50 times and record the number of heads. The numbers of heads are plotted in a histogram.

Two hundred students in a statistics each roll a die 40 times and record the sum of the numbers they got on the 40 rolls. They make a histogram of the 200 sums.

One thousand randomly chosen people report their annual salaries, and these salaries are plotted in a histogram.

The selling price (in $) for the deluxe and standard model Ryobi wood sanders are shown for a sample of eight retail stores. Does the data suggest the difference in average selling price of these Ryobi models is more than $10 at alpha=.1

For the hypothesis stated above (in terms of Deluxe-Standard)

Question 1: What is the test statistic

Question 2: What is the conclusion

Question 3: What is the p value? Fill in only one of the following statements: If the z table is appropriate, p value = If t table is appropriate, Pvalue is between what two values

I understand that it is t problem as sigma is unknown. I am having a problem determining degrees of freedom and test statistic

People are mixed up on the first day of orientation, when they should actually be seated according to their roll number. But they can only move to an empty seat either to their left, right, front or back. If given a starting configuration, will we manage to get everyone seated roll number wise(iterated with rows given a higher priority over columns)? For simplicity, the empty seat is always the (n,n)th element of a nxn matrix. The final configuration should also leave that seat empty

Input Format

The input will consist of n^2 values. The first input gives the value of n and the subsequent (n^2 - 1) inputs correspond to the students' roll number (and their current seated position as determined by the index[0,n^2-1]. Row has a higher priority than column). The maximum value of n in the test cases is 64

Constraints

The runtime of the code in python should be under 20s and in C/C++ should be under 4s

Output Format

You need to return a single digit. 0 if the configuration can not be solved. 1 if the configuration can be solved

A runner sprints around a circular track of radius 130 m at a constant speed of 7 m/s. The runner's friend is standing at a distance 260 m from the center of the track. How fast is the distance between the friends changing when the distance between them is 260 m? (Round your answer to two decimal places.)

Locate two current (within the last 12 months) advertisements -- one that you consider to be "the worst" and one that you consider to be "the best." (Each must be from different media types, both must be from American media, and actual source documentation must be provided for where and when the ads ran.)  Note: ads that ONLY appear on YOUTUBE can not be used.

1. Prepare a two page typed critique discussing why you find one ad bad and the other ad great. Also state how you would correct the bad ad.
2. Post this assignment in the Discussion Board for Week 5 using the "Module Five - Final Project" link above.
3. Respond to ad presented by a fellow classmate - not just agreeing or disagreeing but also expalining why.

You have three unlabeled vials each containing a trichlorobenzene isomer. In order to correctly identify each compound and properly label its container you have taken their 13C nmr spectra. Match at least ONE of the spectrum characteristics in the right-hand column below with a compound from lefthand column. Justify your answer! Draw the molecule that you matched. (7 pts) (a) 1,2,3-trichlorobenzene (i) Two peaks between 125 and 140 ppm (b) 1,2,4-trichlorobenzene (ii) Six peaks between 125 and 140 ppm (c) 1,3,5-trichlorobenzene (iii) Four peaks between 125 and 140 ppm

1. How does the center of mass velocity of the two objects which collide change during an elastic collision? Inelastic collision? Explain.

2. In an inelastic collision, the forces between the two gliders are equal and opposite according to newtons 3rd law. What makes the energy gained by one object unequal (less) than the energy lost by the other in an inelastic collision?
