A study found that 1 out of 200 adult males have green eyes. If a random sample of 400
adult males is obtained, is the sampling of the sample proportion of males that have green
eyes approximately normal?
Solution :
p = 200 / 400 = 0.5
np(1-p)
10
400 * 0.5 * 0.5 = 100
Satisfied the condition .

Assume that the proportion of green eyes in the world's population is approximately 080. A random sample of thirty people is taken, and six of the thirty have green eyes. A) Using the normal approximation to the binomial, find the probability of finding six people with green eyes in a sample of thirty B) Repeat part A, but this time use the binomial distribution instead of the normal approximation. C) Compare your results from parts A and B. Does the...
The proportion of Canadians with green eyes is 0.36. As part of a study of the genetic basis for skin sensitivity to sunlight, a research term collects a simple random sample of 300 Canadians. Answer the following questions to 4 places past the decimal. a) How many people in the sample would you expect to have green eyes? b) What is the standard deviation of the sample proportion? (Use the normal approximation from now on). c) What is the probability...

Out of a random sample of 200 youth, 50 are found to be careless drivers. Out of a random sample of 400 adults, 64 are found to be careless drivers. a. Determine, at a 1% significance level, if there is good evidence that the proportion of youth who are careless drivers is different than the proportion of adults who are careless drivers b. Form a 99% confidence interval for the difference in proportion of youth and adults who are careless...
The proportion of Canadians with green eyes is 0.4. As part of a study of the genetic basis for skin sensitivity to sunlight, a research term collects a simple random sample of 600 Canadians. Answer the following questions to 4 places past the decimal. c) What is the probability that the sample proportion will exceed 0.42?
The distribution of heights of adult males has a mean of 69 inches and a standard deviation of 4 inches. A random sample of 36 adult males is selected. Describe the sampling distribution. a. Since the sample size is greater than 30, the sampling distribution is approximately normal with a sample mean of 69 inches and a sample standard deviation of 9 inches. b. Since the sample size is greater than 30, the sampling distribution is approximately normal with a...
