ounces. Suppose the standard deviation is known to be
\sigma
6.5 ounce. Assume that in the population of all babies born in this hospital, the birth weights follow a Nomal distribution, with mean
\mu
. The standard deviation of the sampling distribution of the mean is a. 6.52 ounces. b. 1.30 esences. c. 0.38 cunces. d. 0.02 ciances. Type a, b, c, d
