If you could write out the answer that would be great.
Transcribed Image Text:A scientist has read that the mean birth weight of babies born at full term is 7.2 pounds. The scientist has good reason to believe that the mean birth weight of
babies born at full term, u, is greater than this value and plans to perform a statistical test. She selects a random sample of birth weights of babies born at full
term and finds the mean of the sample to be 7.5 pounds and the standard deviation to be 1.6 pounds.
Based on this information, complete the parts below.
