1 Q2 Q3 Q4 Q5 Q6 Q7 Q8 Q9 Q10 Q11 Q12 A. On page 2, consider the first five tables. Each is a data set. Answer the following questions for each data set: What type of data is used? (qualitative/quantitative and discrete/continuous?) What graph and/or chart would be useful in describing the data in each table? B. For Table 1: Construct appropriate charts. Describe the data set. Which situation occurs the most often? The least often? What percentage do not have correction? C. For Table 3: Construct three appropriate charts. What is the mean salary? the median? the mode? What is the range? the standard deviation? What are the lower and upper quartiles? Write a paragraph or so to completely describe the starting salaries of these grads. Include a statement about the salary that the new grads should they expect (based on this information.) D. For Table 6: The physical layout of a warehouse must be carefully designed to prevent vehicle congestion and optimize response time. (The layout assumes that vehicles do not block each other when they travel within.) Warehouse operations were simulated; the number of vehicles was varied and the congestion time was recorded. The researchers wanted to investigate the relationship between congestion time and number of vehicles. Construct a scatterplot for the data. Is there a linear relationship between the number of vehicles and the congestion time? What is the equation of the straight line? Identify the slope? Is it positive or negative? Interpret. What is the coefficient of determination? The correlation coefficient? Interpret. Predict the congestion time for 16 vehicles.
