rit factor}.r that manufactures bolts is performing a gualitv control experiment. Each object should have a length of no more than 16 centimeters. The factorv believes that the length of the bolts exceeds this value and measures the length of 54 bolts. The sample mean bolt length was 15.06 centimeters. The population standard deviation is known to be or = 0.28 centimeters. What is the test statistic 2.\"? EX: 1.23 What is the \"gt-value\"?I Eti- {1.123 Does sufficient evidence exist that the length of boltWIv greater than the mean value at a significance level of or = 0.01
