Assume that the sample is a simple random sample obtained from a normally distributed population of fight delays at an airport Use the table below to find the minimum sample sice needed to be 95% confident that the sample standard deviation is within 20% of the population standard deviation A histogram of a sample of those arrival delays suggests that the distribution is skewed, not normal. How does the distribution affect the sample size? to be 95% confident that s is 1% 5% 10% 20% 30% 40% 50% 4 within of the value of the sample size 19.205 768 152 41 21 12 8 n should be at least 1% 5% 10% 20% 30% 40% 50% 33,210 1.336 336 85 35 22 14 To be 59% confident that is within of the value of e, the sample size n should be at least The minimum sample sizs needed in
