Ara's grade is the 80th percentile, in which class interval she belongs?How likely it is that a mean from a particular sample is representative of the population is defined as: t-score F-statistic z-score p-value
- Identify the lower class limits, upper-class limits, class width, class midpoints, and class boundaries for the given frequency distribution. Also, identify the number of individuals included in the summary. (Type integers or decimals. Do not round. Use ascending order.)

- The distribution of the arrival times of students coming to Chemistry class late is not normally distributed. A sample of 33 students is taken, with mean, μ=3.2 and standard deviation, σ=8.4. Is Central Limit Theorem applicable in the following cases? Explain why.11. A company manufacturers batteries in batches of 29 and there is a 3% rate of defects. Find the mean number of defects per batch. Show work.As a data collection specialist at the Centers for Disease Control and Prevention. you have been involved in a research study conducted over the past year. The study found that liver cancer rates per 100, 000 males among cigarette smokers versus nonsmokers in a major city were 58.0 to 25.4, respectively. 1) Using the data above, calculate the relative risk of males developing liver ter for smokers as compared to nonsmokers (round to two decimal places). 2)Create a pie chart to display the risks between the two groups presented. Include characteristics of good graphic design with appropriate labels and titles.
- An appliance company measured customer satisfaction among a randomly selected group of customers who had recently purchased a new dishwasher (n = 20) using a scale from 1 to 5, with 1 equal to a low level of satisfaction and 5 equal to a high level of satisfaction. The results are listed below. 1, 1, 1, 1, 2, 2, 3, 3, 3, 3, 3, 3, 4, 4, 4, 4, 5, 5, 5, 5 Describe, in detail, the appropriate frequency distribution graph for the provided data.Scenario: Is there a relationship between amount of time at a job (X) and productivity (Y)? The researcher quantified amount of time at a job by ranking the employees from those who had been there the least amount of time to the most. The researcher quantified productivity as rating the employees from "best" to "worst". Question: What is the most appropriate statistical test to conduct given this scenario? Pearson's r correlation Spearman correlation Point Biserial correlation Phi correlation9.) Look back at the information in the previous question, but assume that you will use 35 samplings to avoid violating the needed assumption to use the central limit theorem. What is the probability of getting a mean evaluation greater than 8? Previous question: 8.) Suppose that Miller Beer samples peopleís perceptions of the quality of Old Milwaukee beer. Respondents are asked to evaluate the beer on a scale of 1 to 10. The modal response is a 9 amongst sampled WisconsinBros, while the mean is 7.7 with a standard deviation of 2. Suppose you conduct 27 samplings to generate your point estimate of 7.7 as the mean evaluation of Old Milwaukee beer. If you want to use the central limittheorem to evaluate the likelihood that the next sampling will generate a mean evaluation greater than 8.0 which of the three assumptions is clearly violated and why (Hint: If you donít think itís the independent oridentical assumption, then it must be the normality assumption)?
