Question

Stop-One.com, a large Internet retailer, is studying the lead time (elapsed time between when an order is placed and when it is filled) for a sample of recent orders. The lead times are reported in days. Lead Time (days) Frequency 0 to under 2 4 2 to under 4 10 4 to under 6 15 6 to under 8 12 8 to under 10 3 Total 44 a. How many orders were studied? b. What is the midpoint of the second class? (Round the final answer to 1 decimal place.) 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 x value to 1 decimal place and y value to the whole number.) x = , y = d. Not available in Connect. e. Not available in Connect. f. Interpret the lead times. Most orders take around (Click to select) days.

00:01 Here i have to first determine the number of others and equation e.
00:07 As you can notice there are 44 orders.
00:16 Now let's want to question b.
00:18 I have to determine the midpoint of the second class.
00:21 The midpoint of the second class is 2 plus 4 over 2, which is 3.
00:37 In question c, i have to find the coordinates of the first class.
00:43 So for the first class, x is 1.
00:51 Y is here.
00:59 D and e cannot be answered...
