trasher [3.6K]

Answer:

a.) 26< a <u>28 </u>  

b.) 4

Step-by-step explanation:

a.) After looking at the age in years collum you can notice that all of ages have a difference of 2. With this you can infer that the missing number is 28.

b.) To find the mean add up all the numbers in the frequency column.

Divide that by the amount of numbers. There are 5 numbers so 20/5=4.

2. n=30/2

second would be (2,15)

3. n=30/3

third would be (3,10)

4.

n=30/4

fourth would be (4,7.5)
