Write
a brief statement that interprets the confidence interval. Choose the correct answer below.There is a
mean weight of newborn girls will fall between the lower bound and the upper bound.
95%
chance that the true value of the population One has
95%
confidence that the interval from the lower bound to the upper bound contains the true value of the population mean weight of newborn girls.Approximately
95%
of sample mean weights of newborn girls will fall between the lower bound and the upper bound.One has
95%
confidence that the sample mean weight of newborn girls is equal to the population mean weight of newborn girls.Expert Solution
