[mrrns]

Hello everyone, I have this question from statistics but I have no idea about how to solve it. I also don't have the exact answers for it (a-b-c). Could you please explain the solution process step-by-step? I really need it. Thanks a lot.

I will show you how to read the chart.

The stem is the start of the number and the leaf is the next digit

In the 1st row under stem it says 2 and under actresses it says 146667. This means the numbers are 21, 24, 26, 26, 26 and 27. Coincidentally there are no actors who age is in the twenties.

2nd row. Stem is 3. For actors the leaf is 98753221. This means the actor ages are 39, 38, 37, 35, 33, 32, 32, 32 and 31. The leaf for the actresses are handled the same way.

Thank you so much for your concern and your reply.

So , the answer for option c is 76 and 62, right? Because 76 and 62 are the two oldest ones among others.

Option for c is NOT 76. You do not have two actors aged 76?

"Age shared by two actors" means that two actors have the same age -- so they want the greatest age that two different people in the list both have, not the oldest two ages. But you;'re right that the oldest two ages are 76 and 62.

No, there is an actress who is 80 years old! But as others pointed out they are not looking for the oldest actor the oldest actress. If they were the answer would be 67 and 80 not 76 and 62!
