Question
Compute the frequency distribution for Oil change wait times (see table below).
Compute
1. Min and max
2. Bin size for 10 bins
3. First bin = min + bin size
4. 9 remaining bin values
5. Use function = FREQUENCY()
The frequency distribution is

there are 200 values
enter the same in column A of excel
In cell A201, type the formula
=MAX(A1:A200)
We get max = 70
=MIN(A1:A200)
we get min = 10
We need to form 10 bins and the rnage of data is 70-10 = 60
Thus the bin size = 60/10 = 6
First Bin = 6 + 10 = 16
The 10 bin values are as follows
70
The cumulative frequency using the formula frequency is as flows
=FREQUENCY($A$1:$A$200,E1)
That id
Wait times Frequency

Total 200
Answer is option b
16 22 28 34 40 46 52 58 6470
The cumulative frequency using the formula frequency is as flows
=FREQUENCY($A$1:$A$200,E1)
