Question

The following frequency table represents the group counts or 60 groups that came into a resterant for one day. what is the 50th percentile of the data. Value Frequency (group court) 1 3 2 2 3 4 4 2 6 3 7 5 8 3 9 3 10 4 11 4 12 5 13 4 15 4 16 4 17 4 18 3 19 2 20 1

Answer 1

The 50th percentile, or the median, of the data is 7.

Step-by-step explanation:

The 50th percentile, or the median, is the value that divides the data into two equal halves.

In this frequency table, there are a total of 60 groups. Since 50% of 60 is 30, we need to find the value that represents the 30th group count.

Looking at the cumulative relative frequency column, we can see that the median is between the 25th and 26th values, which are both 7.

Therefore, the 50th percentile of the data is 7.
