Question
To assess the accuracy of a laboratory scale, a standard weight that is known to weigh
1.00 gram is repeatedly weighed 36 times. The resulting measurements (in grams) are shown to
the right. Assume that the measured values arenormally distributed. Use these data to compute
a 95% confidence interval of the mean.
1.00 gram is repeatedly weighed 36 times. The resulting measurements (in grams) are shown to
the right. Assume that the measured values are
a 95% confidence interval of the mean.
