To find the missing relative frequency, we need to remember that the sum of all relative frequencies should equal 1.

We can sum the given relative frequencies and subtract the total from 1 to find the missing frequency:

$0.08 + 0.20 + 0.30 + 0.10 + 0.08 = 0.76$

Now, subtract this sum from 1:

$1 - 0.76 = 0.24$

Thus, the missing relative frequency is 0.24.

2. How do you calculate the total frequency from a relative frequency table?
3. What is the difference between relative and cumulative frequency?
4. How can relative frequency be useful in probability?
5. How would you graph the data from this table?

Tip: Always verify that the sum of relative frequencies equals 1 to ensure the table is complete and correct.
