Approximately 36% of people in the United States have a blood type of O+. assume that a sample of size 195 is drawn and the proportion p of individuals in the sample with O+ blood is calculated. Find the probability that a sample proportion is within 3% of the true population proportion 36%. Round the answer to 4 decimal places.
Added by Valerie C.
Step 1
The formula for the standard deviation of a sample proportion is sqrt[(P(1 - P) / n], where P is the population proportion and n is the sample size. In this case, P = 0.36 and n = 195. So, the standard deviation is sqrt[(0.36 * 0.64) / 195] = 0.035. Show more…
