In the study of a certain aquatic organism, a large number of samples were taken from a pond, and the number of organisms in each sample was counted.  The average number of organisms per sample was found to be two.  Assuming that the number of organisms follows a Poisson distribution, answer the following... a)  If we were to look at the next 3 samples, what is the average number of organisms? b) If we were to look at the next 3 samples, what is the standard deviation of the number of organisms? c) What is the probability that in the next 3 samples taken will contain one or fewer organisms?

Section F: In a random sample of 150 unemployed males, 81 of them stated that they were regular consumers of alcoholic beverages. Let p denote the true proportion of unemployed males that are regular consumers of alcoholic beverages.

question 4 only

These next questions come after part B.   Which of the statements correctly describes the relationship between the mean and median in the histogram of the number of servings of fruit per day claimed by the 7474 seventeen‑year‑old girls?   A) The mean and median are about equal because the distribution is right‑skewed.   B) The mean is larger than the median because the distribution is right‑skewed.   C) The median is larger than the mean because the distribution is right‑skewed.   D) There is not enough information to tell us about the relationship between the mean and median in the histogram.   (c) In general, you cannot find the exact values of median, quartiles, or mean from the histogram.   What is special about the histogram of the number of servings of fruit that allows you to do this? Select an answer choice.   A) We know exactly how many observations fall in each bin because of the way the bins are constructed.   B) The sample size only consists of only 74…
