A small vendor has either a good day of sales with an average of $1,000 or a bad day with an average of only $500 for the day. To simulate these outcomes, random numbers from 00 to 99 should be assigned with the intervals determined from the frequency distribution. If, during the last 100 days, the vendor had 27 good days and 73 bad days, which of the following is a correct random-number interval for a bad day?
A) 28 to 99
B) 27 to 73
C) 27 to 100
D) 27 to 99
E) 00 to 26

To find the interval for a bad day, we need to find the range of random numbers that correspond to bad days.
The vendor had 73 bad days out of 100, so the interval for bad days will be from 00 to 99 with the range of bad days falling from the 27th to the 99th number.

Therefore, the correct random-number interval for a bad day is from 27 to 99 which is option D.
