conditions necessary to use the test are: 1. random sample 2. normally distributed population and normal sample distribution. Yes, the conditions are satisfactory for the z test. C. Calculate your test statistic and P-value. Show your work, including the formulas you use to calculate the statistic. (2 points) z = (x-bar – mu)/ (st.deviation/ sqrt. Of n ) = 3.4 – 3.3 / (.4/ (sqrt. Of 50) ) = 1.7677 Now find the p value = .0384 D. What's your conclusion using α = .05? (2 points) Because it is

1. Introduction A Sample survey was collect to verify the mean population in united stated of America lower that the state with highest population. The sample for 50 states was analyzed through one tailed (left) t-static hypothesis. The hypothesis tests and the confidence intervals that we will use for estimating the mean are base on a static called the t-static. A statistical hypothesis itself is an assumption for a set of data which may or may not be true. The null and alternate hypotheses would

UNIT #5 DISCUSSION DQ #1: Data collection is one of the most challenging steps that prevent learners from completing their dissertation. What challenges do you foresee in collecting your data? What are some strategies you’ll deploy to overcome these challenges? a) Challenges in collecting data Reliability and validity In data collection, reliability and validity of the data are important considerations, which a researcher should pay attention to. Reliability, in this case, can be described

Question: Due to financial hardship, the Nyke shoe company feels they only need to make one size of shoes, regardless of gender or height. They have collected data on gender, shoe size, and height and have asked you to tell them if they can change their business model to include only one size of shoes – regardless of height or gender of the wearer. In no more 5-10 pages (including figures), explain your recommendations, using statistical evidence to support your findings. The data found are below:

& Itti, 2017, p. 174). The SVM algorithms were trained and then tested on the same image pairs that were used by the human experiments, and the results were compared with the mathematical goal relevance model. Descriptive Statistics The experiments provided descriptive statistics for each of the tests that were conducted. For the human experiments, whereby the participants were required to give a response based on choosing a left or right path around an obstruction, the researchers calculated inter-subject

The chapter 6 from the book "The Drunkard’s Walk: How Randomness Rules Our Lives" by Leonard is “False Positives and Positive Failures”. At first, it discusses Thomas Bayes theory of conditional probability, and there are some conspiracy theories confuse the direction of conditional. Then it tells that Richard price created actuary science, however, the wise way is updating posterior probabilities after evidence and prior probabilities, and it is important to ask the rate of false positives for diagnostic

Findings and Statistics The comparison between demographic and physiological data was found on Table 1. The statistics showed that there was no significant difference between both the control group and the combined intervention group in relation it age, BMI, years of education, and VO2max fitness. The only shown difference

Final Project – Seasonal Trading Patterns Timothy Brady Southern New Hampshire University 25 January 2015 QSO510 – Quantitative Analysis Professor Ozcan Topic Selection For my paper, I wanted to analyze the validity of the Efficient Market Hypothesis and evaluate patterns in trading. As an investor, one of the fundamental measures that I use is the tendency of commodities to follow seasonal patterns due to the nature of planting and harvesting periods, supply/demand, and general weather
