And we can find this probability with the complement rule:
b)
And if we use the z score we got:
Step-by-step explanation:
Let X the random variable that represent the lengths of a population, and for this case we know the distribution for X is given by:
Where and
Part a
We are interested on this probability
And we can use the z score formula given by:
And using this formula we got:
And we can find this probability with the complement rule:
Part b
For this case we select a sample of n =44 and the new z score formula is given by:
And if we find the z score we got:
And if we use the z score we got:

Answer: 10.53%
Step-by-step explanation:
George £89400 @ 9% = £8046 so income = £89400+£8046=£97446
Harris (Paris?) gets £447 more so 97446+447=£97893
and this represents sales of £89400 plus commission
so Harris' commission = £97893-£89400 = £8493
So last stage is what commission percentage is £8493 of original sales £89400 = 10.53%
