Question
An SRS of 25 recent birth records at the local hospital was selected. In the sample, the average
birth weight was x = 119.6 ounce Suppose the standard deviation is known to bes = 6.5 ounces.
Assume that in the population of all babies born in this hospital, the birth weights follow a Normal
distribution, with mean m. Based on the 25 recent birth records, the sampling distribution of the
sample mean x can be represented by:
a. N(119.6, 1.30).
b. N(119.6, 6.5).
O c. N(m, 1.30).
O d. N(m, 6.5).
