Transcribed Image Text:Here are summary statistics for randomly selected weights of newborn girls: n=36, x=3180.6 g, s = 700.5 g. Use a
confidence level of 95% to complete parts (a) through (d) below.
CITT
a. Identify the critical value to/2 used for finding the margin of error.
fa/2=
(Round to two decimal places as needed.)
b. Find the margin of error.
E= g
(Round to one decimal place as needed.)
c. Find the confidence interval estimate of μ.
<<
g
(Round to one decimal place as needed.)
d. Write a brief statement that interprets the confidence interval. Choose the correct answer below.
OA. Approximately 95% of sample mean weights of newborn girls will fall between the lower bound and the upper
bound.
OB. 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.
OC. There is a 95% chance that the true value of the population mean weight of newborn girls will fall between the
lower bound and the upper bound.
OD. One has 95% confidence that the sample mean weight of newborn girls is equal to the population mean weight of
newborn girls.
