Question: The breaking strengths of 14 randomly selected objects produced from a standard procedure had a mean of 56.43 and a standard deviation of 6.30. In

The breaking strengths of 14 randomly selected objects produced from a standard procedure had a mean of 56.43 and a standard deviation of 6.30. In addition, the breaking strengths of 20 randomly selected objects produced from a new procedure had a mean of 62.11 and a standard deviation of 7.15. Perform a hypothesis test to investigate whether there is sufficient evidence to conclude that the new procedure has a larger breaking strength on average than the standard procedure.
