A study was conducted and it was reported that 34 34 out of 253 253 students said they had an all-nighter in the last semester. We will assume that random sampling is used and that the sample is less than 10 % 10% of the population. Verify the sample size condition so that we may assume that the sampling distribution of the sample proportions is approximately normal. ^ = n p ^ = ( 1 ^ ) = n(1 p ^ )= Yes, the sample is large enough. No, the sample size is not large enough
