A federal inspector for weights and measures visits a package plant to affirm that the net weight of packages is as indicated on the packages. The plant manager assures the inspector that the packaging process results in a mean weight of 760 grams and a standard deviation of 6 grams. The inspector selects 64 packages at random and finds their mean weight to be 758 grams. If the manager's statement is correct, how likely is a sample mean of 758 grams or more? After finding the probability that the sample mean is at least 758 grams, indicate the interval below that contains this probability. .0500 to .0999 .7500 to .9500 .1000 to .7499 0.9501 to 1.000 .0000 to .0499
