Ahypothesis regarding the weight of newborn infants at a community hospital is that the mean is 6.6 pounds. a sample of seven infants is randomly selected and their weights at birth are recorded as 9.0, 7.3, 6.0, 8.8, 6.8, 8.4, and 6.6 pounds. what is the alternate hypothesis?

The alternate hypothesis is that newborn infants has a mean weight of 7.56 pounds.

Step-by-step explanation:

Let's find an alternate hypothesis by using the formula:

mean=(sum of all data)/(number of data points) so:

sum of all data=9.0+7.3+6.0+8.8+6.8+8.4+6.6=52.9 and:

number of data points=7 so:

mean=52.9/7=7.56 pounds

The alternate hypothesis is that newborn infants has a mean weight of 7.56 pounds.
