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.
