Walden Wk 7 Effect of Maternal Psychiatric Disorders Depression Anxiety Questions
This exam will consist of 20 multiple-choice or true/false questions randomly chosen from a test bank. No two students will have the same exam. You will have 5 hours to complete the exam. This exam consists of two parts. In the first part, you will enter your exam answers to the 20 questions into the Blackboard Exam area. For the second part of the exam, you will submit a supporting document that shows your work and/or reasoning for each of your exam answers. For each exam answer, you should show the calculations, reasoning, or justification for how you arrived at your exam answer. This document must be submitted no later than 2 hours after completing and submitting the exam answers in Blackboard, and it will be submitted to a separate Week 7 Exam Supporting Document submission area. This supporting document does not have to follow APA formatting requirements and will not be graded separately;

Statistics Discussion
Give an example of an interval estimate of an average or proportion you may use in your daily life. For instance, you may say that you are pretty sure your average commute time is between 25-30 minutes, or you are fairly confident that between 60-65% of the population love dogs. Collect some data to see how well your intuition is working. First, does your sample data meet all assumptions necessary to construct the confidence interval of the type you need? Even if it doesn’t, construct and interpret the confidence interval.

this is a correct example of the question:"A confidence interval is a range of values so defined that there is a specified probability that the value of a parameter lies within it. In statistics, a confidence interval is a type of estimate computed from the statistics of the observed data. This proposes a range of plausible values for an unknown parameter. The interval has an associated confidence level that the true parameter is in the proposed range. Between driving to work and providing morning transportation for my nanny, I estimate the average amount of miles I drive per week is about 200 miles. Calculating my Confidence Interval, adding 14.8 miles to and from work are equal to 29.6 miles per workday, 7.8 miles to and from my Nanny’s house equal to 15.6 miles per workday day and altogether the daily workday mileage, including transportation for my nanny, is 45.2 miles. In addition, misc. mileage, such as trips to the grocery store, equal an average of 10 miles per work week – as the grocery store is extremely close to home. 45.2 miles four times a week is 180.8 miles per work week. 180.8 plus 10 for misc. mileage is 190.8 The amount of mileage on two my days off has been represented numerically by “0” and the other with “10” to compensate for the misc. mileage. Ending with:Mean (?): 27.257142857143Standard deviation (?): 20.947202823347Weekly Mileage Data Set:45.2, 0, 45.2, 45.2, 45.2, 0, 10Weekly MileageWeek DaysMileage Per DayMonday45.2Tuesday0Wednesday45.2Thursday45.2Friday45.2Saturday0Sunday1095% Confidence Interval: 27.26 ± 15.5(11.8 to 42.8) "With 95% confidence the population mean is between 11.8 and 42.8, based on only 7 samples."

business statistics - critical thinking question finding descriptive statistics and making report
Finer Suit Company sells suits in the US and the European Union. The
company monitors its suit sales by collecting randomly chosen data from
store locations throughout the US and the EU. They record list price (in
dollars), sale price (in dollars), and number of days it takes to sell
each suit. Data were collected from 200 suits sold in the US and 200 in
the EU region. The complete data set is in the file named Suits.Managerial ReportPrepare a report (see below) that summarizes your assessment of the
nature of the suit market in each region. Be sure to include the
following seven items in your report.Calculate descriptive statistics (mean, median, range, standard
deviation, and coefficient of variation) to summarize each of the three
variables for the all US suits. Use z-scores to determine if there any
outliers in the data set for any of the three variables.
If there are any outliers in any category, please list them and state for which category they are an outlier.If a result is an outlier, state whether it is below or above the mean.How can one use the above descriptive statistics to understand the
US suit market better? Could there be any other descriptive statistics
that can help one understand the US suit market better?

MC 621 KKC UIC Correlation and Regression Analysis Questions
In a test of a weight loss program, weights of 40 subjects are recorded before and after the program. Assume that the before/after weights result in r = 0.876.Is there sufficient evidence to support a claim of a linear correlation between before/after weights?Does the value of r indicate that the program is effective in reducing weight? Why or why not?*Comment on your classmates postings by comparing and contrasting your results. Below is my classmate post.The value of r being 0.876 would align closest with alpha being 0.1 and n being 7. This wouldn't make an impact on the graph showing weights before and after, and wouldn't be in correlation with the data given. We don't know what the starting weights were, or the ending weights were to determine if the data shows that the program is effective or not. I don't think that the r represents or indicates that the program is even effective.
