(a)
The description about the population distribution.
(a)
Answer to Problem 16E
The population distribution is approximately a binomial distribution with p = 0.75.
Explanation of Solution
Given information:
Number of white beads = 1000
Number of red beads = 3000
Number of beads for SRS = 50
Mean of the
Standard deviation = 0.06
To find the total population, add the number of white beads and red beads that is, 1000 beads and 3000 beads.
Find the proportion of red beads by dividing 3000 by 4000.
The above population distribution is approximately a binomial distribution with
Hence, the population distribution is approximately a binomial distribution with p = 0.75.
(b)
The description about the sampling distribution of
(b)
Explanation of Solution
Given information:
Number of white beads = 1000
Number of red beads = 3000
Number of beads for SRS = 50
Mean of the Normal distribution = 0.75
Standard deviation = 0.06
The values of sample proportion
This means that the sampling distribution of
Also, in the given data the sampling distribution of
The sampling distribution differs from the population distribution by its Normal distribution.
