3. A study was done using a random sample of n = 25 expectant mothers to see if an experimental supplemental diet for the mothers will increase birth weights on average. The average birth weight
of
the n=25 babies whose mothers participated in the study was a = 8 pounds. Find the probability
that the sample mean has a value of 8 or greater.

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4
