Use the given degree of confidence and sample data to
construct a confidence interval for the population mean µ.
Assume
that the population has a normal distribution.
please show ur work, thanks
Hi Dear,
I have given my 100% to solve your problem.
So, please help me out by just thumbs up.
Thank you, so much
