Side-by-side dotplots are very useful in visualizing the within-sample variation, the between-sample variation, and the relationship between them.

Q. 2The number of successes observed during the n trials of a binomial experiment is called the binomial random variable.
Indicate whether the statement is true or false
Q. 3The mathematical model for a particular problem is an equational statement showing the anticipated makeup of an individual piece of data.
Indicate whether the statement is true or false
Q. 4A binomial experiment is a sequence of n identical trials such that each trial (1) produces one of two outcomes that are conventionally called success and failure and (2) is independent of any other trial so that the probability of success or failure is constant from trial to trial.

Q. 5A single-factor ANOVA is applied to three independent samples having means 8, 11, and 16, respectively. If each observation in the third sample were increased by 20, the value of the F-statistics would:
a. increase
b. decrease
c. remain unchanged
d. increase by 20
Q. 6A binomial probability distribution shows the probabilities associated with possible values of a discrete random variable that are generated by a binomial experiment.
Indicate whether the statement is true or false
Q. 7The F-statistic in one-way ANOVA represents the:
a. variation between the treatments plus the variation within the treatments.
b. variation within the treatments minus the variation between the treatments.
c. variation between the treatments divided by the variation within the treatments.
d. variation within the treatments divided by the variation between the treatments.
