This problem is fill in the blank.  Just choose the correct answers.  Thank you for your help   A scientist has read that the mean birth weight, μ, of babies born at full term is  7.2 pounds. The scientist, believing that μ is less than this value, 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 6.9 pounds and the standard deviation to be 1.7 pounds.   Based on this information, answer the questions below. What are the null hypothesis (H0) and the alternative hypothesis (H1) that should be used for the test? H0:  (choose one) less than, less than or equal to, greater than, greater than or equal to, equal to, or not equal to.      (choose one)      6.9 pounds, 7.2 pounds, or 1.7 pounds.
