Extracted text: A manager is interested in determining if the population standard deviation has dropped below 128. Based on a sample of n= 23 items selected randomly from the population, conduct the appropriate hypothesis test at a 0.10 significance level. The sample standard deviation is 115. Determine the null and alternative hypotheses. O A.

There is insufficient evidence that the population standard deviation is less than 128. O B. Do not reject Ho. There is sufficient evidence that the population standard deviation is less than 128. O C. Reject Ho. There is sufficient evidence that the population standard deviation is less than 128. O D. Reject Ho. There is insufficient evidence that the population standard deviation is less than 128.
