MAT 232 Ashford University The Normal Distribution Discussion
You will find Video 6: The Normal Distribution by navigating to the MSL Tool for Success link under Course Home.This video explains the normal distribution via the binomial distribution: The distribution of the number of heads thrown on 20 coins approximates the normal. This is used to explain that the normal distribution is the mathematical consequence of adding up a large number of random events. Some examples are given of normal distributions in the natural world (mass of ants) and social world (age of marathon runners) and explained in terms of these phenomena resulting from the aggregation of random events.Respond to one of the following questions in your initial post:What is the link between the normal distribution and Video 5: Variation 2 (and Egg Roulette), where we relied on statements such as “about two-thirds of observations are within one standard deviation of themean”?Do natural phenomena such as hemoglobin levels or the weight of ants really follow a normal distribution? If you add up a large number of random events, you get a normal distribution.How large a number makes a normal distribution?Your initial post should be 150 to 250 words in length.Video 5 Link: https://mediaplayer.pearsoncmg.com/assets/6fOkITxn...Video 6 link: https://mediaplayer.pearsoncmg.com/assets/_jGvVe5J...Transcript for both videos attach below

statistic analysis
Your response should be 400-750 words, in APA format, 12pt font, 1" margins, references page, etc. (abstract not required). Make sure to use a .doc, docx, or rtf file format and attach the file when submitting. Also, these assignments have a minimum of five (5) required sources. While the source report can count as one source, this means you need to find additional sources to add detail and support to your answers. Look for real world examples in the news, peer reviewed journals, etc. For more information about the assignments, refer to the assignment and its grading rubric on Blackboard.Prompt:Below is a chi-square and Cramer’s V statistic from Maricopa County’s Sheriff Offices’ Annual Report (2014-2015). The tables tests the relationship between whether a driver had an item seized by that driver’s race. The chi-square is significant, so a relationship exists. What does this tell us about the Maricopa County Sheriff's Office? How does the Cramer’s V weigh in here? In other words, according to this data, does MCSO discriminate based on race? If so, which races and how much does race account for seizures?Driver post-stop perceived race or ethnicity WhiteUnknownNative AmericanHispanicBlackAsianTotalDriver item seized - No187472714015671198856927647Driver item seized - Yes268223131475476Total190152734245802203557428123Chi-Square64.29** Cramer's V0.048** + p < 0.10; * p <0.05; ** p < 0.01

Statistic Questions
1. To determine whether a new sleeping pill has an effect that varies with dosage, a researcher randomly assigns adult insomniacs, in equal numbers, to receive either 4 or 8 grams of the sleeping pill. The amount of sleeping time is measured for each subject during an 8-hour period after the administration of the dosage. What type of design is this, and what type of statistic is needed to analyze the data?2. Dr. Bill Board designs a 2 X 2 between-subjects factorial design, where Factor A is word frequency (low or high) and Factor B is category cues (no cues or cues). Assume that the data are interval. What type of statistic is needed to analyze the data.

ITEC 8437 WU Inferential Statistics One Sample T Test Male Professors Age Essay
A t test examines if two means (averages) are reliably different from each other; that is, whether any significant differences exist between the means of samples from different populations. For example, to what extent is the output of a local office which applied an IT solution different than the output of other local offices which did not apply the IT solution? Also, if you wanted to test whether the average IQ score of a group of students differs from 100, you may use a t test. A t test does more than just compare means; as an inferential statistic, t tests allow researchers to make inferences about the populations beyond their sample data.For this Assignment, you will use the IT Security database and conduct two t tests: (a) one-sample t test and (b) paired-samples t test and prepare an APA results write-up for each test....thank you
