Answer:
The answer is : 0.0597
Step-by-step explanation:
Population mean = μ = 80
Standard deviation = σ = 20
Sample = N = 60
σ_mean = σ/√N
= (20)/√(60) = 2.582
Now we will find z1 and z2.
z1 = {(84) - μ}/σ_mean = 
z2 = {(88) - μ}/σ_mean = 
Now probability that the sample mean will be between 84 and 88 is given by:
Prob{ (1.549) ≤ Z≤ (3.098) } = (0.9990) -(0.9393) = 0.0597
M= 48.16666666666667. You can verify by multiplying it by 54, and comparing it with 51x51 and see if you get same results.
Answer:
1/2
Step-by-step explanation:
Die : 1,2,3,4,5,6
Less than 4: 1,2,3
P (less than 4) = Number of options less than 4/ total
