you need to find how much they can make per hour so b can make 3.5 in 1 hr and n can make 4 and 8 is the equivalent that the amount of hrs it takes to make 60 leashes
Answer:
A) probability that at least x of them will require repairs is less than 0.5 is 4
Step-by-step explanation:
sample size, n = 20
p = success probability of toaster = 0.2
q = failure probability of toaster =1- p = 1- 0.2 =0.8
mean, , μ = n * p = 20 * 0.2 = 4
standard deviation,
a) the probability that at least some of them require repairs < 0.5.
for value of z = 0
we know
from z table
X = 4
B) SECOND PART IS INCOMPLETE { DATA IS INCOMPLETE}
