You are welcome to submit a paper responding to the film linked for extra credit, 1989’s Glory. Write a brief reflection on the film. The reflection is NOT meant to be a blow-by-blow summary or a riff on published film reviews. Apart from a very brief overview of the film (a paragraph), you need to write YOUR impressions of the movie, based on what you have learned in class so far. Describe specific scenes or characters to help you be specific in your impressions–selectively. Be sure to reference ideas from the course content that relate to the film. Your reflection on the film should be 1-2 pages, double spaced. Follow standard formatting as listed in other writing assignments.This assignment will be given up to 25 points, based on quality and originality of your response.

Don’t worry too hard about a conclusion on this draft. You only have one class period to get this going!  The most important thing to do is to practice writing on a first draft and get your thoughts down on paper.

The Revenue Commissioners in Ireland conducted a contest for promotion. Statistics from the ages of successful and unsuccessful applications are given below. Some of the unsuccessful applicants charged that the competition involved discrimination based on age. Assume the data were normally distributed.  Sample size Sample mean Sample standard deviation Ages of unsuccessful applicants 26 47 7.2 Ages of successful applicants  30 43.9 5.9 Construct a 95% confidence interval for the difference between the mean age of the successful applicants and the unsuccessful applicants. Show detailed work for the following steps: (6pts)  a) Calculator command:  b) Information input:  c) Confidence interval (round to 1 decimal place):  d) Interpretation:   

Find the indicated probability. Round the answer to 4 decimal places. (3pts) You are dealt two cards successively without replacement from a shuffled deck of 52 playing cards. Find the probability that both cards are black.    

A cereal company claims that the mean weight of the cereal in its packets is 14 oz. The weights (in ounces) for the cereal in a random sample of 8 of its cereal packets are listed below. 14.6       13.8        14.1     13.7       14.0      14.4      13.6       14.2   Assume the sample comes from a normal distribution population. Test the claim at the 0.01 significance level. (14pts) Round the sample mean and the sample standard deviation to 2 decimal places. Perform the following steps:  (3pts) Step 1: Requirements (2pts) Step 2:                 (3pts) Step 3: Test statistic (round to 3 decimals) (3pts) Step 4: p- value (round to 4 decimals) (2pts) Step 5: P- value Method  (1pt) Step 6: Conclusion  

Use the given degree of confidence and sample data to construct a confidence interval for the population mean μ. Assume that the population has a normal distribution.A sociologist develops a test to measure attitudes towards public transportation, and 27 randomly selected subjects are given the test. Their mean score is 76.2 and their standard deviation is 21.4. Construct the 94% confidence interval for the mean score of all such subjects using a calculator command. Make sure to include correct symbol, formula and round off rule for each step.

Find the indicated probability. (4pts)The participants in a television quiz show are picked from a large pool of applicants with approximately equal numbers of men and women. Among the last 12 participants there have been only 4 women. If participants are picked randomly, what is the probability of getting 4 or fewer women when 12 people are picked? Make sure to first define variable X, then calculate the probability Define variable X=
