 A manufacturer of power tools claims that the mean amount of time required to assemble their ... 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 wordQ. 2The 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?Q. 3A 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.
