How does a multinomial distribution differ from a binomial distribution?
 a. A binomial has only two possible categories and a multinomial can have more.
  b. A binomial has a fixed number of n trials. A multinomial has a fixed number of nk trials, where k is the number of categories.
  c. The probabilities in a binomial distribution are always p and 1 - p. The trials in a multinomial distribution are always p/k and (1 - p/k).
  d. All of these choices are true.

Q. 2

We can use the payoff table to calculate the expected monetary value (EMV) and the expected opportunity loss (EOL) of each act (alternative).
  Indicate whether the statement is true or false

Q. 3

How do you calculate the expected frequency for one cell in a goodness-of-fit test?
 a. The expected frequency is equal to the proportion specified in H0 for that cell.
  b. Use the total number of observations divided by the number of categories.
  c. Multiply the specified proportion for that cell (found in H0) by the total sample size.
  d. None of these choices.

Q. 4

If your control chart found a series of points all lying within 3 standard errors above the center line, and none lying below the centerline, this could be an indication of assignable variation due to a(n) ____________________.
 Fill in the blank(s) with correct word

Q. 5

Which of the following represents H1 in a chi-squared goodness-of-fit test to see if all 5 colors of a certain candy appear in the same proportion in the population?
 a. H1: p1 = p2 = p3 = p4 = p5 = .20.
  b. H1: At least one proportion is not equal to .20.
  c. H1: None of these proportions are equal.
  d. None of these choices.

Thank you

Can you answer the others that I've posted too? :sweat:

I'll take a quick look at them
