A bolt manufacturer is very concerned about the consistency with which his machines produce bolts. The bolts should be 0.23 centimeters in diameter. The variance of the bolts should be 0.02. A random sample of 26 bolts has an average diameter of 0.22 cm with a standard deviation of 0.1445. Can the manufacturer conclude that the bolts vary by more than the required variance at a = 0.025 level? Step 1 of 5: State the hypotheses in terms of the standard deviation. Round the standard deviation to four decimal places when necessary. Answer Ho: Ha: Keypad Keyboard Shortcuts Tables
