The binomial probability distribution is an example of discrete probability distributions.
  Indicate whether the statement is true or false

Q. 2

The number of degrees of freedom for the denominator in one-way ANOVA test involving 4 population means with 15 observations sampled from each population is:
 a. 60
  b. 19
  c. 56
  d. 45

Q. 3

If x is a binomial random variable with n = 20, and p = 0.5, then P(x = 20) = 1.0.
  Indicate whether the statement is true or false

Q. 4

In a single-factor ANOVA, if the numerator and denominator degrees of freedom are 4 and 25, respectively, then the total number of observations must equal:
 a. 24
  b. 25
  c. 29
  d. 30

Q. 5

The binomial random variable is the number of successes that occur in a certain period of time or space.
  Indicate whether the statement is true or false

Q. 6

Which of the following statements is false regarding a single-factor ANOVA?
 a. Between-sample variation and within-sample variation are compared in an ANOVA test.
  b. The data values from repeated samplings are called replicates.
  c. SS(total) = SS(factor) + SS(error)
  d. None of the above

Q. 7

As a rule of thumb, if the sample size n is large relative to the population size N in particular, if n / N >= 0.05 then the resulting experiment will not be binomial.
  Indicate whether the statement is true or false

Q. 8

The test statistic in the single-factor ANOVA equals the ratio
 a. sum of squares for factor sum of squares for error.
  b. sum of squares for error sum of squares for factor.
  c. mean square for factor mean square for error.
  d. mean square for error mean square for factor.
