The weight of a newborns is normally distributed with standard deviaiton is 2.000. A hypothesis regarding the weight of newborn infants at a community hospital is that the mean is 6.0 pounds. A sample of four infants is randomly selected from a normal distribution and their weights at birth are recorded as 7.0, 8.0, 5.0, and 6.0 pounds. What is the decision for a statistical significant change in average weights at birth if the critical values are -2.000 and 2.000?...

4. (25 points) The average weight of new born babies at a hospital is stated to be 6.6 pounds. A sample of seven babies is randomly selected and their weights are recorded as 9.0,7.3,6.0, 8.8,6.8, 8.4, and 6.6 pounds. Given that the sample variance is 1.386, test if the average weight is equal to 6.6 pounds at 5% level of significance.

In 2012, the Journal for Obstetrics and Gynecology reported that the mean weight of all babies in the U.S. was 7.45 pounds. A doctor was concerned that the birth weight of babies delivered at a local hospital was significantly below the national average. The doctor examined n = 35 recent births at the hospital and found that the mean birth weight was 7.3 pounds with a standard deviation of 0 pounds. The distribution of the 35 birth weights was skewed to the right. The...
