Suppose a company issues a press release announcing a new line of business that has a positive NPV of $30 per share of stock outstanding. In an efficient market, what will happen to the stock price at the time of the announcement? What will happen to the stock price in the days following the announcement assuming no new news becomes available about the company? Explain your responses.

Draw a labelled sketch showing how the eye works and which parts of the eye see variations of contrast, color and detail (include rods and cones in your sketch). What does the “blind spot” mean and where is it in the eye? Does the eye see an upright or an inverted image? How does the lens of the eye work? Is the lens static?

1) what are Cauchy’s Integral Theorem and Cauchy's integral formula

2) Explain about the consequences and applications of these theorems.

3) Explain about different types of singularities and the difference between Taylor series and Laurent series.

Please Use Matlab to do this problem:

The cross-sectional area measurements (??2) from 7 cells are as follows:

? = [153.3 91.2 99.3 115.0 101.7 135.8 102.4 ]

Assuming the cross-sectional areas of the cells are normally distributed, construct a two-sided 95% confidence interval for the mean cross-sectional area of the entire batch.
Then, generate one figure:

• Plot all 7 data points on x-axis, mark them with red circles;

• Plot the mean value, which is going to be the center of your interval, mark it with

  blue x;

• Plot the upper and lower limit of the interval, mark them with black squares;

• Have your x-axis range from 70 to 180;

• Have your y-axis range from -1 to +1. (So, your x-axis will be in the middle of

  your figure)

• You can play with the line width and font to make your figure more reader friendly.

Do you get more for your money by buying loose or prepackaged carrots? 40 random packages of carrots, labeled “1 pound” were selected from 8 different grocery stores and weighed to the nearest gram. (Note: grams were used as the unit of measurement so that the measurement could be more precise. One pound is equivalent to 454 grams.) The sample mean weight was 512.2 grams with a standard deviation of 39.3 grams. Is there evidence that the mean weight of a “1 pound” bag of carrots weighs differently than 454 grams (the equivalent of 1 pound)

a. Define the parameter(s) and state the hypotheses.

b. What would be a good graph to display the data from this study?

c. Are the conditions for the appropriate analysis met? Explain and show work or attach a graph if appropriate.

d. Compute the appropriate test statistic (show work). (3 points)

e. How many degrees of freedom does the test statistic have?

f. Find the p-value.

g. Based on your p-value, what do you conclude? Use  = 0.01.

h. Construct a 90% confidence interval for the mean weight (in grams) of a “1 pound” bag of carrots. Write a sentence interpreting your confidence interval.

Question 1

Question 2

Question 3

Which of the following solutions is considered hypotonic? (Points : 3)

Question 4

A good purpose statement for this lab is: The purpose of this lab experiment is to show that water molecules move from high to low concentration; the water will move by osmosis. (Points : 2)

Question 5

It is not necessary to take measurements of the water in the potato in this lab, you can see if there is a change (osmosis) just by looking at it. But you would want to collect data for the results in a written lab report.

Question 6

The graph or chart (results) with the information for this lab should include: beginning and ending data, labels, units and times of measurement if written in a formal lab report.

Question 7

The conclusion is usually the longest section of a lab report. This is the section where you explain or analyze the results you found.

Question 8

Question 9

The cell membrane around the potato cells is permeable to water molecules. This explains why the salt does not move into and out of the cells but the water molecules do........... raising (increasing) the water level.

Question 10

Evidence to support osmosis in this lab might include the water level rising inside of the potato filled with salt water.

Question 11

In your osmosis/potato lab, the molecules of salt are the solute.

Question 13.

In your osmosis/potato lab the mixture of the salt and water is the solution.
