b) Exhibit 2 shows the histogram and Exhibit 3 gives a table of summary statistics for the individual’s age of those included in the data. i) From Exhibit 2, with examples, provide three essential items that could improve the above chart. ii) From Exhibit 3, What is the median value and how do you obtain it. iii) From the answer you provided in part (ii) and based on Exhibit 2 and Exhibit 3, describe the shape of the distribution of this data. Give some intuitive explanation for why this data produces this shape. c) Use Exhibit 3 to interpret in context the central tendency of the smoker’s “Age”. d) i) Write down the formula for the sample standard deviation and using the sample variance from Exhibit 3 calculate the standard deviation value. Show all workings. ii) Other measures of the spread/dispersion of the data are the Range, Interquartile Range and Coefficient of Variation. From Exhibit 3, calculate the Range IQR, and CV Give interpretations for…

1. Given the data set: {3, 5, 6, 9, 4,7,4,2,3,9, 1, 3, 8} provide the following rounded to two decimal places if needed) The mean а) b) The median The mode c) The range _The midrange d) e The five number summary f) g) A box and whisker plot: draw below using the provided number line for scale. 3 6 10 1 2 4 7 89 h) Is this data set skewed_yes - positive/right, yes - negative/left or no - symmetric (circle one) _The standard deviation (O i) j) Most of the data in the set above are between - 6 and u6. Calculate these values and verify this statement based on the set above. k) According Chebyshev's Theorem, what fraction of the set lie within 2 standard deviations of the mean? Verify this based on the set above
AFDA Main Ideas: Module 9 Review 1) The measures of center: 2) Measures of spread: 3). When describing a data set, the mean is used with used with 4) Z-scores are used to compare data that is 5). What is the formula for finding the z-score? 14 6). The z-score of the mean is always z = 7). What are the characteristics of a normal distribution? and and and the median is 8). What two characteristics make a distribution go from "normal" to "standard normal?"
The length of fish were measured at 3 different lakes. Is there evidence to suggest that the average length is not the same at all 3 locations? Lake 1: 3.5, 4.2, 2.1, 3.2, 1.7 Lake 2: 5.1, 6.2, 5.3,4.1 Lake 3: 5.6, 7.1, 6.4, 7.1, 6.4 What is your conclusion? There is not evidence that the mean length at one of the lakes is different then the others. There is evidence hat the mean length at a least one lake is different then the others.
