17. According to the Central Limit Theorem, a distribution of sample means based on a sample of n= 7 will approximate normality even if the data in the parent population are not normal. 18. When performing hypothesis tests or computing confidence intervals based on large samples, it is necessary to assume that the data in the parent population(s) are distributed normally. 19. To estimate u within two units with 95% confidence and o= 10 requires n be at least 100.
