Post by: Tiffhazz on Mar 10, 2018 A manufacturer of power tools claims that the mean amount of time required to assemble their top-of-the-line table saw is 80 minutes with a standard deviation of 40 minutes. Suppose a random sample of 64 purchasers of this table saw is taken. The probability that the sample mean will be greater than 88 minutes is ________.
Fill in the blank(s) with correct word Q. 2 The amount of tea leaves in a can from a particular production line is normally distributed with = 110 grams and = 25 grams. What is the probability that a randomly selected can will contain between 82 and 100 grams of tea leaves? What will be an ideal response?
