Path: pA soft drink filling machine, when in perfect adjustment, fills the bottles with 12 ounces of soft drink. A random sample of 25 bottles is selected, and the contents aremeasured. The sample yielded a mean content of 11.88 ounces, with a standard deviation of 0.24 ounces. With a 0.05 level of significance, test to see if the machine isin perfect adjustment. Assume the distribution of the population is normal.

The provided information is as follows:The average mean sample is 12 ounces.The sample size n is…
