Complete Question
Find the mean, variance, and standard deviation of the binomial distribution with the given values of n and p. , The mean, , is nothing. (Round to the nearest tenth as needed.)
p = 0.6 n = 18
Answer:
The mean
The standard deviation
The variance
Step-by-step explanation:
From the question we are told that
The probability of success is
The sample size is
Generally given that the distribution is binomial, then the probability of failure is mathematically represented as
substituting values
Generally the mean is mathematically evaluated as
substituting values
The standard deviation is evaluated as
substituting values
The variance is evaluated as
substituting value
Answer:
(351.04, 368.96)
Step-by-step explanation:
Given that population mean= 360
Std devitaion = 4
margin of error = 2.5%= 0.025
Since population std deviation is known we can use Z critical value
For two tailed critical value for 2.5% would be
2.24
Margin of error = ±Critical value*std deviation
= ±2.24(4)
= ±8.96
Confidence interval =(Mean - margin of error, mean + margin of error)
=
