The probability will be found as follows:
z-score is given by:
z=(x-μ)/σ
where:
mean-μ=9.3
standard deviation-σ=1.1
but
σ/√n=1.1/√70=0.1315
thus the z-score will be:
z=(9.1-9.3)/0.1315
z=-1.5209
thus:
P(x<9.1)=P(z<-1.5209)=0.0643
The answer is 43. What I did was I added all the numbers together, and since they wanted the area, and to find the area you multiply TWO numbers together, I multiplied the sum by 2 and I got 43. Hope this helps!
