Question

Here are summary statistics for randomly selected weights of newborn​ girls:

n=36​, x=3211.1​g, s=689.4g. Use a confidence level of 95​% to complete parts​ (a) through​ (d) below.
 
a. Identify the critical value tα/2 used for finding the margin of error.
 
tα/2=enter your response here
​(Round to two decimal places as​ needed.)
Part 2
b. Find the margin of error.
 
E=enter your response here
g
​(Round to one decimal place as​ needed.)
Part 3
c. Find the confidence interval estimate of
μ.
 
enter your response here
g<μ<enter your response here
g
​(Round to one decimal place as​ needed.)
Part 4
d.
Write
a brief statement that interprets the confidence interval. Choose the correct answer below.
 
A. 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.
 
B. One has 95​% confidence that the sample mean weight of newborn girls is equal to the population mean weight of newborn girls.
 
C. Approximately 95​% of sample mean weights of newborn girls will fall between the lower bound and the upper bound.
 
D.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.
