6 due to new variable which is sample size and mention of proportion) 7 (use the p formula if it is about proportion) A sample of >> what is the prob. >> ch. 7: packaging equipment is filling 368-gram (i. e. 13oz) cereal boxes. It is set so that the amount of cereal in the box is normally distributed with mean of 368 grams. From past experience the population standard deviation for this process is known to be 15 grams. A sample of 25 boxes is randomly selected from many thousands that are filled in a day and the average weight is computed for this sample. What is the probability that the sample of. ** if it doesn"t say normal distribution and sample size is less than 30 you can not proceed with this question. Z = 365 368 / (15/sr25) = -1 >> 0. 1587. Z = 368-368 /(15/sr25) = 0 >> 0. 5000.
