Answer:
Mean = 8
Variance = 7.36
Standard Deviation = 2.7129
Step-by-step explanation:
This is a binomial distribution with parameters, n and p.
Where
n is sample size (given as 100)
p is the probability of success, or probability of defective (given as 8% or 0.08)
The mean, variance, standard deviation formula for binomial distribution is shown below:
Mean = 
Variance = 
Standard Deviation = 
Where q would be probability of failure, or "1 - p"
Thus,
n = 100
p = 0.08
q = 1 - 0.08 = 0.92
SO, we have:
Mean = 
Variance = 
Standard Deviation = 
Answer:
20
Step-by-step explanation:
x - 9 = 11
+9 +9
x = 20
Answer: b (-3, 1]
explanation:
Answer is given below
Step-by-step explanation:
given data
average length of all 1015 fishes = 98.06 mm
randomly selects 50 fishes average length = 101.04 mm
solution
- When we get here, we mean to measure, so here we measure a fish in a square lake.
- And the variable means that a fish varies from fish to fish, so the length of the fish in the squares
- parameter mean that all individuals in the population so the parameter is average length of all 1015 fish in square lake
- statics is selct of individual in sample so statistic is average length of random sected so fish in square lake
Sum= positive 30 because you add the opposite
The difference between the numbers is also 30
