Answer:The correct option is a)
The upper limit of successes that would be deemed to be usual is 5, so more than 5 successes would be unusual.
Step-by-step explanation:
The mean of a binomial distribution
μ= np where n=10 and p= 0.2 q= 1-p, q= 1-0.2=0.8
μ= 10×0.2=2
σ=√npq
σ=√10×0.2×0.8=1.26
Is unusual for the number of success to be greater than μ + 2.5σ.
= 2+2.5(1.26)
=5 approximately.
So it is unusual for it to be greater than 0.5. The right option Is a)
Answer:
A good estimate for the slope is 95/60
Step-by-step explanation:
The formula to calculate the slope between two points is equal to
From the graph take the points
(0,0) and (80,125)
substitute
simplify
Multiply by 3.75 both numerator and denominator
therefore
A good estimate for the slope is 95/60
You graph it at the coordinates. Unless there was a drawing pad you can't really draw it out.
