What is the mean of the set of data (average number of hours worked)? C. What is the median of the set of data? d. What is the range_(difference between the maximum and minimum values)? e. What is the Inter Quartile Range or IQR (difference between Q3 and Q1)? Number of Hours Worked per Week Frequency 24 Work Question 9./ a. Looking at ONLY the histogram how would you describe the shape of the distribution...in other words, does the histogram look symmetrical (normal), skewed left, or skewed right? OR would you say that the shape is unclear by looking only at the histogram? b. Explain how you arrived at your answer. 10. a. Using the values from the Mean and Median (found earlier) can you now give a better answer to #9a? What would you now conclude concerning the shape of the distribution? b. In this situation, would you say that the mean or the median is the better predictor of central tendency? Explain your answer!Himmnuimni- Worm-h9- 14. Looking at ONLY the histograms how would you describe each of these data sets__.in other words, does the histogram for the price of a child's ticket look symmetrical, skewed left, or skewed right? Give your opinion on all four of the histograms this is only an opinion at this point.

Were your initial thoughts on the shape of the four graphs correct or would you now change your mind after seeing the actual mean and median of each of the data sets? After reading the descriptive statistics how would you now characterize the shapes of EACH of the histograms? Based on the standard deviation which item's cost is the most consistent? In other words, which item tends to cost relatively the same at all parks? How did you come up with your answer? 25-; 26. FF" 27'. FF\" d. e. Tickets padlhg Which of the data sets (ticket cost or parking cost] contains outliers? How can you tell? Based only on the hoxplot display: which would he the better predictor of central tendency for each data set: the mean or the median? How do you know\"? Which set of data [ticket cost or parking cost) has the larger dispersion {range}? For ticket cost.-.25% of the park's admission cost is GREATER than what amount? For ticket oost___the rst quartile or 25% ot the park's admission cost is LESS than what amount? For ticket cost what is the IDR...\" InterQuartile Range\"? How did you come up with your answer? For parking cost...?5% of parking cost is GREATER than what amount? For parking cost___5{l% of parking cost is LESS than what amount
