determine whether the result appear to have statistical significance and also determine whether the results would appear to have practical significance in a study of a gender selection method used to increase the likelihood of a baby being born a girl 2077 users of the method gave birth to 1021 boys and 1056 girls there's about a 23% chance of getting that many girls if the method had no effect. because there is a 23% chance of getting that many girls by Chance the method blank blank couples would likely use a procedure that rises the likelihood of a girl from approximately 50% rate expected by the chance to the blank percent produced by the method so this method blank

The Stoneytown School District covers 4 towns. There are 14 members of the school board, and the 4 towns have the populations shown in the following table:

1. The school district uses the Hamilton method to apportion its 14 board members to the 4 towns. How many board members are assigned to each town, using this method?
2. The following year, 1,000 people move out of Town B and into Town D. Now, how many board members does each town have? (Be careful. Make sure you assign a total of 14 board members).
3. Compare the results from the 2 years. Do you think they make sense? Are they fair? Why or Why not?

Please solve the following breakeven analysis problem and show all systems of equations and work. (Excel solver is not neccessary for this problem)

Jim and Pam are going to Culinary School! There are a group of students at the school who are drug dealers, and the Captain has received information that they are looking to start selling a dangerous new street drug to the residents of the town nearby. Jim and Pam infiltrate this group and propose that they use the school’s kitchens in the evening (5-10pm, 7 days/week) to cook and deliver food to the town’s residents and use the deliveries to sell drugs. The group seems to be on board with this plan, so our boys just need to start and operate the business for some time so that they can gather information and evidence for their investigation.

Jim and Pam will need a van for the deliveries, so the Captain agrees to spend $4,300 on a used van for them. In order to look like a legitimate business, they will pay their employees $8/hour for the 5-10pm shifts. For now, they only have one student working each evening. Each delivery will cost $1.35, and they expect that each orders meals will cost $15 on average to prepare and will bring in $34 in revenue.

A. The Captain wants them to wrap up the investigation in 2 months (8 weeks). How many meals would they need to make and deliver to breakeven on the cost of the van?

B. As it turns out, Jim is very talented in the kitchen and really enjoys Culinary School. His crème brulee is the talk of the town. But when the cooking becomes more important to him than the case, it doesn’t look like they’ll be able to wrap up the investigation in 2 months. The Captain is not happy and gives Jim an ultimatum: they only have one more month to gather enough evidence to make the arrests or they’re fired! What is the breakeven point for the business over 3 months (12 weeks)?

You will perform a Two Sample Hypothesis Test for Means. For the Hypothesis Tests, make sure to report the following steps:

Identify the null hypothesis, Ho, and the alternative hypothesis, Ha.

Determine whether the hypothesis test is left-tailed, right-tailed, or two-tailed.

Find the critical value(s) and identify the rejection region(s).

Find the appropriate standardized test statistic. If convenient, use technology. Decide whether to reject or fail to reject the null hypothesis.

Interpret the decision in the context of the original claim.

Question: A science teacher claims that the mean scores on a science assessment test for fourth grade boys and girls are equal. The mean score for 63 randomly selected boys is 151 with a standard deviation of 36, and the mean score for 65 randomly selected girls is 149 with a standard deviation of 34. At α = 0.10, can you reject the teacher’s claim? Assume the populations are normally distributed and the population variances are equal.
