a manufacturer must test that his bolts are 5.00cm long when they come off the assembly line. he must calibrate his machines if the bolts are too long or too short. after sampling 49 randomly selected bolts off the assembly line, he calculates the sample mean to be 4.88cm. he knows that the population standard deviation is 0.44cm. assuming a level of significance of 0.01, is there sufficient evidence to show that the manufacturer needs to recalibrate the machines? step 2 of 3 : compute the value of the test statistic. round your answer to two decimal places.

p-valueis 0.0562>0.05, there is enough data to conclude that the machines’manufacturershould perform a newcalibration.## What is test statistic?

statisticemployed in statistical hypothesis testing is known as a test statistic. A test statistic, which can be thought of as anumericalsummary of a data set that condenses the data into a single value that can be used to conduct the hypothesistest, is how a hypothesis test is commonly expressed.p-valueis 0.0562>0.05, indicating that there is enough data to conclude that the machines’manufacturershould perform arecalibration.teststatistic,
