characteristics of Sampling Proportions If the sample size n is large and p is not too close to 0 or 1, then Sampling Distribution of Proportions is approximately normal. Generally, we need np 210 and n(1-p) ≥ 10 in order for the normal approximate to be reasonable. Example 12 Suppose 57% of all adults in US between 35-40 years of age exercises at least 4 days per week. If we take a random sample of 90 adults between 35-40 years, what is the probability that more than 45% of them exercise at least 4 days per week? Page 12 of 12
