Step-by-step explanation:
do the right first
then subtract
It’s 12.6, the top and bottom sides are parallel to each other.
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
