Southern New Hampshire University Statistics Discussion

Option 2: A professor states that in the United States the proportion of college students who own iPhones is .66. She then splits the class into two groups: Group 1 with students whose last name begins with A-K and Group 2 with students whose last name begins with L-Z. She then asks each group to count how many in that group own iPhones and to calculate the group proportion of iPhone ownership. For Group 1 the proportion is p1 and for Group 2 the proportion is p2. To calculate the proportion you take the number of iPhone owners and divide by the total number of students in the group. You will get a number between 0 and 1. What would you expect p1 and p2 to be? Do you expect either of these proportions to be vastly different from the population proportion of .66? Would you be surprised if p1 was different than p2? Would you be surprised if they were the same or similar? What statistical concept describes the relationship between the first letter of someone's last name and whether or not they own an iPhone? STUDENT 1: Respond to this students discussion post in response to Option 2 (above) I would expect that the percentage of iPhone users in both P1 and P2 to be similar. I think this might also depend on weather or not the college students are from the same area, or the same college. Overall, I'd expect them to be about the same even though P2 has more people in the sample. I would expect the proportion to be a little bit higher than the population proportion. I say this because I think college students tend to invest in technology a little bit more than the average person. They use computers and phones constantly, so they may be more inclined to go for the Apple products due to popularity. I would be pretty surprised if P1 was vastly different than P2. I wouldn't see why a random sample like this would yield two different results. This sample seems very random, so I would think it would yield similar results. I would not be surprised if they were similar at all. The concept in this problem is Probability, in this case .66 or 66%.

Complete the following end of chapter exercises for Chapter 3. Submit your response in an MS Word document or Pdf after inserting the results from SPSS Output into your document. This exercise utilizes the data set schools-a.sav, which can be downloaded from chapter data sources referenced above.1- You are interested in investigating if being above or below the median income (medloinc) impacts ACT means (act94) for schools. Complete the necessary steps to examine univariate grouped data in order to respond to the questions below. Although deletions and/or transformations may be implied from your examination, all steps will examine original variables.a. How many participants have missing values for medloinc and act94?b. Is there a severe split in frequencies between groups?c. What are the cutoff values for outliers in each group?d. Which outlying cases should be deleted for each group?e. Analyzing histograms, normal Q-Q plots, and tests of normality, what is your conclusion regarding normality? If a transformation is necessary, which one would you use?f. Do the results from Levene’s test for equal variances indicate homogeneity of variance? Explain. 2- You are interested in studying predictors (math94me, loinc93, and read94me) of the percentage graduating in 1994 (grad1994).a. Examine univariate normality for each variable. What are your conclusions about distributions? What transformation should be conducted?b. After making the necessary transformations, examine multivariate outliers using Mahalanobis distance. What cases should be deleted?c. After deleting the multivariate outliers, examine multivariate normality and linearity by creating a Scatterplot Matrix.d. Examine the variables for homoscedasticity by creating a residuals plot (standardized vs. predicted values). What are your conclusions about homoscedasticity?Please use APA format with references.

MTH410 Colorado State University Week 4 Hypergeometric Discussion Board

As a manager of an organization, what probability distribution from this week would you use if you wanted to estimate or study an aspect of your employee turnovers? Explain why you would use it. In your post, be sure to specifically identify the statistical formulas and what additional data you would need to determine your estimate(s). Some aspects of employee turnovers may be time employed, number of annual turnovers, time until the first turnover of the year, etc.Here are the probability distributions that we have covered. Discrete:Hypergeometric—See Section 4.1 as to when you may use it.Binomial—See Section 4.2 as to when you may use it.Poisson—See Section 4.4 as to when you may use it.Continuous:Uniform—See Section 5.2 as to when you may use it.Exponential—See Section 5.3 as to when you may use it.Normal—See Sections 6.2 and 6.3Do not forget to explain why your probability distribution applies.22 mins ago
