A bolt manufacturer wants to investigate the machine that produces bolts with a diameter of 0.21 centimeters. If the variance of the diameters is equal to 0.015, then the machine is working as expected. A random sample of 10 bolts has a standard deviation of 0.0535. Does the manufacturer have evidence at the a = 0.05 level that the variance of the bolt diameters is less than required? Assume the population is normally distributed. Step 1 of 5: State the null and alternative hypotheses. Round to four decimal places when necessary. Answer Ho: Keypa Keyboard Short Tables
