Sample size less than 15: Use t procedures if the data appear close to Normal (roughly symmetric, single peak, no outliers). If the data are clearly skewed or if outliers are present, do not use t. Sample size at least 15: The t procedures can be used except in the presence of outliers or strong skewness.

Sample count. For any sample size, the sample count X is binomial. When sample size is small, it is convenient to find the probability distribution of X using binompdf on your calculator. (X takes integer values from 0 to n.) Sample proportion. For any sample size, the sample proportion is not binomial but it is closely related since = X / n.

The compliance testing sample size table above is based on a 5 percent tolerable exception rate for both nonmonetary and monetary attributes. If program materiality is set lower than 5 percent, then the tolerable exception rate would be lowered, and the minimum sample sizes may need to be adjusted upward.

What if the sample size was 40 for the 99% confidence interval in (a). How would the confidence interval change with this larger sample size? No calculations necessary. The confidence interval would be the same width but shifted to the left.

From the sample size, we record the count X of “success” ( here infers the victim over 65 years old). The X should be 287. D. The total sample size is 350. 35. E. Since the P-value is a probability, so it must be between 0 and 1. 36. C Note that we are taking 50 independent observations from the distribution.
