- What is a sample space?If the lower boundary (i.e. lower fence) = 7 and there is a value 2 in a frequency of 5 (e.g. 2, 2, 2, 2, 2), would the total outlier count be "five" or would it be "one." I assume it would be "five" since there are five data values of "2" that are less than the lower boundary. Thanks in advance for providing insight on this.Determine the mean, median and mode for the sample of masses of students. Show all work, use proper notation and provide a therefore statement.
- An article describes a survey of 2,096 adult Americans. Survey participants were asked if they were football fans and also if they agreed or disagreed that the rules that the National Football League adopted in 2010 designed to limit head injuries have been effective. Data from the survey are summarized in the table below. Agree Disagree Total Football Fan 673, 543, 1,216. Not a Football Fan 199, 681, 880. Total 872, 1,224, 2,096. Suppose that a survey participant is to be selected at random. Consider the following events. A = event selected participant agreed that the rules have been effective D = event selected participant disagreed that the rules have been effective F = event selected participant was a football fan (a) Calculate the following probabilities. (Round your answers to four decimal places.) (i) P(A) = (ii) P(D) = (iii) P(A|F) = (iv) P(A|FC) = (b) Are the events F and A independent events? Justify your answer using relevant probabilities. Yes, the events F and A are…In a small company there are 8 accountants , 14 engineers and 6 clerks .

- If a study determines the difference in average salary for subpopulations of mechanical engineers and civil engineers is NOT significant, then the subpopulations of mechanical and civil engineers are ________ different salaries. Guaranteed not to be earning 2.Earning very 3.Definitely earning 4.0Not earningA major problem with the survey method is: a.Obtaining enough information in a short amount of time. b.Obtaining a representative sample of subjects to be questioned. c.That it cannot reveal very much about significant social events in the lives of the people tested. d.Identifying the group to be questioned. Please with detailed explanationSuppose a, b, c, d, e, f are data set of nonnegative integers such that the midrange is5 and the mean is 6. Find all the possible median of the given data set that satisfiesthe following:i) the mode is a bimodal,ii) the lowest value is unique, andiii) the highest value is unique.
- Find the mean, median and mode of the given set of numbers: 2, 5, 3, 6, 4, 9, 7, 6, 9, 11 Select one: Mean=6.2, Median=6, Mode=6 and 9 Mean=6.2, Median=6.5, Mode=6 and 9 Mean=6.2, Median=6, Mode=6 Mean=6.2, Median=6, Mode=9 Mean=6.2, Median=12, Mode=6 and 9A data is collected from Lab A, and this data is considered as the reference (standard). Sample mean is 12, SD is 2.4 and sample size if 16. Another set of data from Lab B have a mean of 10, SDB is 2.4 and nB=16. If we choose α = 0.05, do you think mean of Lab B is close enough to be considered the “same” as that of Lab A? Why?5. Suppose a quarterback’s completion percentage for the season is 67.2%.
