According to the manufacturer of a certain candy, 9% of the candy produced are red. If we take a random sample of 100 bags of the candy, what is the probability that the proportion in our sample of red candies will be less than 20%? Which one of the following conditions for using the Central Limit Theorem for Sample Proportions is not met?
A.
If the sample is collected without replacement, ten the population size must be at least 10 times bigger than the sample size.
B.
The sample is randomly selected from the population and the observations are independent of each other.
C.
The sample size is large enough that the sample expects enough success and failures.
Homework Answers
Correct option is :
C.
The sample size is large enough that the sample expects enough success and failures.
(since np=100*0.09 =9 ; which is less than 10)

A. Suppose you take a sample of size n from a population and calculate a statistic from that sample. The statistic could be a sample proportion p, a sample mean x, or another statistic. Then suppose we repeat this process over and over again until we find all possible samples of size n from the population (this is a theoretical idea) and we calculate the same statistic from 1. each sample. The collection of all of the statistics calculated is...

Which of the following is not a true statement? Question 10 options: a) The Central Limit Theorem will work for skewed data, but the more skewed the data, the more data needed. b) When working with proportions, we do not need to worry about whether or not our successes/failures are greater than 10. c) The Central Limit Theorem depends upon independent observations. d) The center of the sampling model will be the true mean of the population from which we...

Consider taking samples of size 100 from a population with proportion 0.33. Is the sample size large enough for the Central Limit Theorem to apply so that the sample proportions follow a normal distribution? a) Yes, np and n(1-p) both >=10. b) No, np and n(1-p) both >=10. c) Yes, np and n(1-p) both >=100. d) No, 100 is never large enough.

Let us assume that the weights of bags of dog food are normally distributed with a mean of 50 lb and a standard deviation of 2.5 lb. (a) Describe the shape and horizontal scaling on the graph of the distribution for the population of all weights of bags of fertilizer. (b) Find the probability that the weight from a single randomly selected bag will be less than 46 lbs. Based upon your results, would it be unusual to find an...
