13) ACME Steel Inc. produces metal rods. Quality control believes that the rods produced in 2021 are not the same length as the rods produced in 2022. The mean length of a sample of 60 rods produced in 2021 is x = 8.43 ft with a sample SD of s = 0.9 ft. The mean length of a sample of 120 rods produced in 2022 is x = 7.95 ft with a sample SD of s = 1.2 ft They test their claim at a 1% significance level. Determine: Ho H p-value p = Decision: Reject H OR Do not reject H 0 0 Conclusion:
