I need a step by step break down on this question please show the steps on how to do it not the mean step by step break down . The last question I ask just showed the answer but not the break down on how you got it.If the Data set of Mangos are: 1,1,2,3,5,5,6,3,2,2,1,01. E ( x^2 -x) please show the work break down with the answer

The last class of data to be examined is grouped data vs. ungrouped data. Differentiate between the two giving an example to assist with your explanation. Given the list of numbers, 13. 15. 19, 21, 12, 18, 16, 15, 17. Find , mean mode, median, range, interquartile range, and standard deviation
The sample data here is the cholesterol levels for 10 men diagnosed with high cholesterol. The first row represents levels from 10 men who did not use the drug and the second row from 10 different men who did use the drug. If we want to test the claim that the mean level for all men who use the drug is less than the mean for all men who do not use it, what is the appropriate alternative hypothesis? The mean cholesterol level of males who take the medicine is higher than the mean cholesterol levels of men who do not take it. There is a significant difference between males who use the medicine and men who do not use the drug in terms of mean cholesterol levels. The mean cholesterol level of males who take the medicine is lower than the mean cholesterol levels of men who do not take it. There is no significant difference between males who use the medicine and men who do not use the drug in terms of mean cholesterol levels.

In a secondary school, a survey was carried out in which we wanted to know the number of hours that students dedicate to study in two semesters. The following results were obtained: a) Prepare a table by class intervals, with 7 intervals that complies with the two Sturges rules b) Include in the table Class Mark, Absolute Frequency, Accumulated Frequency, Relative Frequency and Accumulated Relative Frequency. c) Determine the Central Tendency Measures (Average, Median and Mode). d) Determine the dispersion measures (Range, Variance and Standard Deviation) e) Calculate the 78th percentile f) Calculate kurtosis index g) Calculate Fisher's skewness index
In Week 1, you were asked to analyze the use of statistics in health care. Now that you have expanded your knowledge base, let’s reexamine that relationship. Have you thought of new ways in which statistics could be incorporated into the work you do? Are there ways in which you could improve processes or patient care using these techniques (related to statistics)? Give specific examples and suggestions.
People often say “Distance makes the heart fonder.” Interestingly, due to pandemic related lockdowns, some persons have been implicitly or explicitly indicating that it is indeed true as they have been struggling with their relationships due to lack of time apart from their partner. A researcher who is interested in such an issue decided to collect data on the level of rage/edginess that exist among a few couples due to lockdowns. Participants were asked to rank the level of hostility they think they have been exerting towards their partner due to having to spend more time than they usually do with them. The resulting data is presented on page two (2). 2 *14 is the highest level of hostility. Level of hostility Number of partners 0-1 4 2-3 11 4-5 8 6-7 20 8-9 25 10-11 12 12-13 12 13-14 4 a.

Water specimens are taken from water used for cooling as it is being discharged from a power plant into a river. It has been determined that as long as the mean temperature of the discharge is at most 150F, there will be no negative effects on the river's ecosystem. To investigage whether the plant is in compliance with regulations that prohibit a mean discharge water temperature above 150F, researchers will take 50 specimens at randomly selected times and record the temperature of each specimen. The resulting data will be used to test the hypotheses:H0:μ≤150FH0:μ≤150F Ha:μ>150FHa:μ>150F.(a) In the context of this problem, describe Type I and Type II errors.Type I Error:Select an answer A Type I error is not obtaining convincing evidence that the mean water temperature is greater than 150F when in fact it is greater than 150F. A Type I error is obtaining convincing evidence that the mean water temperature is greater than 150F when in fact it is at most 150F. Type II…

A restaurant owner decides that more than half of their customers prefer chocolate ice cream because chocolate is the mode when customers are offered their choice of chocolate, vanilla, and strawberry. you are trying to decide if the restaurant owner is using the correct term to describe the data set. Set up two data sets, one where the restaurant owner is correct and one where the restaurant owner is false. Explain why the restaurant owner is not using the correct definition for the term (Mean, Median, or Mode) that they picked
