Answer:
14.2, 16.96
Step-by-step explanation:
given is a probability distribution of X
X is discrete taking values as 7, 11, 15 and 19
X 7 11 15 19 total
p 0.10 0.35 0.20 0.35 1
x*p 0.7 3.85 3.0 6.65 14.20
x^2*p 4.9 42.35 45 126.35 218 .60
Hence mean = sum of prob (x) = 14.20
9times sq root of 14 or 33.67492

<u>Sharmaine had an income of US$ 1,355 that week.</u>
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
