A new machine is set or calibrated to fill tubes of toothpaste at precisely 6.75 ounces. Then, once the machine is running, a sample of six tubes is taken every three hours and weighed with the following results:      WEIGHT OF TOOTHPASTE Time 7 am 6.69 6.68 6.79 6.77 6.74 6.76 10 am 6.71 6.72 6.71 6.76 6.75 6.74 1 pm 6.66 6.68 6.67 6.71 6.76 6.78 4 pm 6.73 6.74 6.72 6.76 6.78 6.75 7 pm 6.75 6.73 6.75 6.77 6.79 6.75 The measurement of quality is based on _______.

In an experiment to determine whether there is a systematic difference between the weights obtained with two different mass balances, six specimens were weighed, in grams, on each balance. The following data were obtained: Specimen A 1 14.86 14.83 2 9.44 9.41 3 11.99 11.99 4 9.27 9.26 5 6.13 6.13 13.78 13.76 It is reasonable to assume that the population of differences is approximately normal. A hypothesis test was carried out to determine if the mean weight differs between the balances. The results from this hypothesis test procedure carried out in Excel are presented below.
