  1. The following data shows birthweights (oz) from seven consecutive deliveries at the Hospital in April 2007: 121 138 32 100 58 64 146
  1. Calculate the sample mean birthweight
  2. Calculate the sample median birthweight
  3. Calculate the sample standard deviation of these birthweights
  4. What population could this sample represent?
  5. Suppose this is a representative sample of births in a given year at Loma Linda Hospital. Suppose, instead of a sample of seven values, we have a sample of 100 birthweights. How should the mean, median, and standard deviation of this sample compare to the same statistics for the sample of seven birthweights?

A list is obtained of birth weights from 30 consecutive, full-term, live-born deliveries from the maternity ward of a hospital in a low-SES area. The mean birthweight (???) is found to be 115 oz. with a sample standard deviation (s) of 24 oz. We know from nationwide surveys based on millions of deliveries that the mean birthweight in the United States is 120 oz. Use the onesample t test to test the hypothesis H0: ? = 120, H1: ? <...
