Arivet is to be inserted into a hole. a random sample of n 15 parts is selected and the hole diameter is measured. the sample standard deviation is strong evidence to indicate that the standard deviation of hole diameter exceeds 0.01 millimeters? use α-0.01. (a) calculate the test statistic xo round your answer to two decimal places (e. g. 98.76) 0.008 millimeters. is there (b) is there strong evidence to indicate that the standard deviation of hole diameter exceeds 0.01 millimeters yes. statistical tables and charts the tolerance is +/-296
