1. Consider the set of odd .in digit integers (1, 3, 5 7, 9}.
a. Make a list of all samples Of size 2 that can be drawn from this set Of integers.. Maniple with replacement; that is, the first number is drawn, observed, and then replaced (returned to the sample set) before the next drawing.]
b. Construct the satripling distribution of sample means for samples of sae 2 selected from this set.
c. Construct the sampling distributions of sample ranges for samples of size 2.
2. if a population has a 8tandard deviation σ of 25 units,. what is the standard error of the mean if samples of size 16 are selected? Samples of size 35? Samples of size 100?
3. According to Nieisen"s Television Audience report,in 2009 the average American biome had 2.86 television sets( More than the average number of people per household, at 2.5 people). if the standard deviation for the number of televisions in a U.S. household is 1.2 and a random sample of 80 U.S. households is selected,. the mean of this sample belongs to a sampling distribution..
a. What is the shape of this sampling distribution?
b. What is the mean of this sampling distribution?
c. What is the standard deviation of this sampling distrfbution?
4. Consider a normal population with μ = 43 and σ = 5.2. Calculate the z-score for an x of 46.5 from a sample of size 16.
5. What is the probability that the sample of kindergarten children (pages 146-147) has a mean height of Less than 39,75 inches?
