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.
3+2+7+8+0=20
Divide that by the amount of numbers. There are 5 numbers so 20/5=4.
Hope this helps!

The intensity level is hard and for the first part, it’s 168. and something. Sorry that’s all I figured out I’m not too smart :/
