Question

construct the frequency distribution for drive - through service times for burger king lunches using the accompanying data set. times begin when a vehicle stops at the order window and end when the vehicle leaves the pickup window. lunch times were measured between 11:00 am and 2:00 pm. begin with a lower class limit of 70 seconds and use a class width of 40 seconds. click the icon to view the drive - through service times. construct the frequency distribution service time (seconds) frequency 70 - 109 4 110 - 149 23 150 - 189 5 190 - 229 1 230 - 269 3 (type whole numbers.) drive - through service times 116 131 147 120 126 130 136 133 121 182 146 138 110 149 148 110 208 120 105 79 91 150 83 102 78 199 198 137 142 70 166 105 253 231 250 102 128 106 84 153 151 145 171 100 124

Explanation:

Step1: Define the first class

The first class has a lower - limit of 70 seconds and a width of 40 seconds, so the first class is 70 - 109. Count the number of data values in this range.

Step2: Define the second class

The second class is 110 - 149. Count the number of data values in this range.

Step3: Define the third class

The third class is 150 - 189. Count the number of data values in this range.

Step4: Define the fourth class

The fourth class is 190 - 229. Count the number of data values in this range.

Step5: Define the fifth class

The fifth class is 230 - 269. Count the number of data values in this range.

Answer:

Service Time (seconds)	Frequency
110 - 149	23
150 - 189	5
190 - 229	1
230 - 269	3
