Can someone help me with my Week 2 Discussion 1 in Math 205 Quantitative Explorations in Everyday Life
Your instructor will assign you to one of the three groups: Group A, Group B, or Group C. Your instructor will also assign you a number. Do the problem based on the number assigned to you by your instructor. Then, respond to at least three different peers from your own group.The actual group discussion will function the same as any other discussion. You will only be able to participate and discuss with those peers assigned to your same group.In order to view your peers’ work and respond to their posts, you need to submit your completed work by Day 4 (Friday). You will not be able to view your group’s posts until after you have replied with your completed problem. Also, re-submissions are not allowed in this class.Your initial post should be at least 250 words in length. It should show all the required math work and explain all the steps. Also include a simple reference for any used resource. For example: Washington Post dated August 13, 2018 or retrieved from .

Deliverable 5 – Optimal Strategy with a Nonzero-Sum Game
CompetencyThis competency will allow you to demonstrate your ability and skill in analyzing nonzero-sum games and synthesizing optimal strategies within them.InstructionsDuring the city’s mayoral race one of the candidates hires G&B Consulting. This candidate is a challenger from the same party as the incumbent mayor and is vying to be put on the ticket in the general election. She believes that the nomination will likely come down to what stance she takes on a proposed tax bill. The bill is for a tax increase that would subsidize education grants. Staying within traditional party lines would be advantageous to gaining support from the core constituency, but going against party lines on the issue would help sway swing voters and independents. The issue is bound to come up at an upcoming debate and she wants the help of G&B Consulting to determine an optimum strategy.InstructionsTo complete this assignment, you must first download the word document .Your step-by-step breakdown of the problems, including explanations, should be present within the word document provided.

(Points : 18)3. (TCO B) A source in the Internal Revenue Service has stated that historically 90% of federal tax returns filed are free of arithmetic errors. A random sample of 25 returns are selected and checked carefully for arithmetic errors. Assuming independence, find the probability thata. all 25 returns are free of arithmetic errors.b. at most 23 returns are free of arithmetic errors.c. more than 17 are free of arithmetic errors. (Points : 18)4. (TCO B) The Bank of Connecticut issues Visa and Mastercard credit cards. The balances on these credit cards follow a normal distribution with a mean of $845 and standard deviation of $270.a. What percentage of balances is below $1,200?b. What percentage of balances is between $600 and $1,000?c. Find the 12th percentile for balance (i.e., find the cutoff for the lowest 12% of balances). (Points : 18)Question 5.6. (TCO C) The personnel manager of a large firm wants to find the percentage of employee absences that occur on Fridays. A random selection of 500 employee absences is taken from work records over the past several years. The data reveals that 220 of the 500 employee absences were on Fridays.a. Compute the 99% confidence interval for the population proportion of absences that are on Friday.b. Interpret this confidence interval.c. How large a sample size will need to be selected if we wish to have a 99% confidence interval that is accurate to within 3%? (Points : 18)8.
