Solution

FIRST QUESTION

First we compute mean = 12 + 6 +15 + 10+ 18+5+5+6+6+3+6+10+ 6+ 7 + 6 15 8.0667Now standard deviation VE (x-x)² (6-8.0667)² - (2-4.0667)?+ (6-8.0667)2 + ... o 4.1

SECOND QUESTION

So have twenty forty 5s thirty ten (remaining) and 7s. So aggregate value of these numbers = 20x4 + 40x5 +30x6+ 1087 1 530
