<span>a)
Z*_Upper = (76 - 62.7)/2.5 = 5.32
Z*_Lower = (57 - 62.7)/2.5 = -2.28
The requirement is to get p(-2.28 < Z < 5.32) = p(Z<5.32) - p(Z<-2.28).
Use normal distribution table to get the answer for p and multiply with 100 to get the percentage.
The other questions are now easy for you to answer on your own. Hope it helps.

Answer:
17 and 44
Step-by-step explanation:
Let S = smaller number, then L = the larger = 3S - 7
The sum = 3S - 7 + S = 4S - 7 = 61
4S = 68
S = 17 and L = 44
