Indicate whether the statement is true or false.
1. For a binomial test, if pn = 10 and qn = 90, then n = 100.
a. True
b. Fals
e
2. For a binomial test with p = 1/2 and n = 36, the z-score for X = 21 is z = +1.00.
a. True
b. Fals
e
3. In a binomial hypothesis test, the value for X must always be a whole number (not a fraction or decimal value).
a. True
b. Fals
e
4. Binomial data exist whenever a measurement procedure classifies individuals into exactly two distinct categories.
a. True
b. Fals
e
5. If other factors are held constant, both the mean and standard deviation for the binomial distribution will both increase
as the sample size increases.
a. True
b. Fals
e
6. For a binomial distribution with p = 1/4 and a mean of m = 12, the standard deviation is s = 9.
a. True
b. Fals
e
7. Assume there are two categories, A and B, and the symbol X stands for the number of individuals classified as
belonging to category A in a sample of size n. X can have any value from 0 to n and each value of X has a specific
probability. The distribution of probabilities for each value of X is called the binomial distribution.
a. True
b. Fals
e
8. In a sign test, dividing the zero differences evenly between the two groups will increase the likelihood of rejecting the
null hypothesis.
a. True
b. Fals
e

9. If p = 1/5, the binomial distribution for samples of n = 100 will have a standard deviation of σ = 4.
a. True
b. Fals
e
10. For a two-tailed binomial test with n = 100, a = .05, and a null hypothesis stating that p = 0.10, a score of X = 13
would be sufficient to reject the null hypothesis.
a. True
b. Fals
e
11. For a binomial test, if pn = 12 and qn = 36, then p = 0.25.
a. True
b. Fals
e
12. For binomial data that satisfy the criterion for using the normal approximation, you can either compute a z-score or a
2
value for chi-square. The relationship between the two statistics is z = χ .
a. True
b. Fals
e
13. The binomial test can be used as an alternative to the chi-square test for goodness of fit provided the observed
frequencies fit in exactly two categories.
a. True
b. Fals
e
14. The binomial distribution with p = .10 has a mean of m = 10. For this distribution, there are n = 100 scores in the
sample.
a. True
b. Fals
e
15. For a binomial distribution with p = 1/2 and n = 30, the value of X ranges from 1 to 30.
a. True
b. Fals
e
16. For a binomial distribution based on n = 100, the standard deviation would be larger for p = 0.90 than for p = 0.80.
a. True
b. Fals
e
17. The binomial test is only used when the data consist of classifying each individual into one of two categories.
a. True

22. If either pn or qn is greater than 10, the test statistic for the binomial test is a z-score and the critical values are
obtained from the unit normal table.
