Answer:
A: The 10 percent condition states that the population is greater than 10 times the sample, or 10n. In other words, the sample size must be no more than 10 percent of the population. In this problem, the sample size is 7, and the population is 38. This means that 38>10n, or 38>10 times 7, or 70. 38 is not greater than 70, therefor the 10 percent condition is not met in this case.
B: In this problem, p, or the population proportion is 14/38. The conditions of normality are that n times p and n times 1-p are both greater than 5. n=38 and p, as stated, equals 14/38. This means that n times p equals 14, and n times 1 minus p equals 24, which are both greater than 5. This means that both of the normality condition have been met.
