(Round the final answer to1declmalplace.) c. What are the coordinates of the first class for a frequency polygon assuming we draw a frequency polygon using the midpoints? {Round the final I: value to1 decimal place and yvalue to whole number.) X = E ' v = l: d. Not available in Connect. e. Not available in Connect. f. Interpret the lead times, Most orders take around days. The Wachesaw Manufacturing Co. produced the following number of units in the last 16 days: 29 28 30 29 28 31 25 28 31 30 25 25 30 30 27 31 The information is to be organized into a frequency distribution. a. How many classes would you recommend? b. What class interval would you suggest? (Round the final answer to 1 decimal place.) c. What lower limit would you recommend for the first class? d. Organize the information into a frequency distribution and determine the relative frequency distribution. (Round the final answers to 3 decimal places.)
