Hello.
The question goes as follows:
On the basis of results obtained from a random sample of 100 flights for a company the 95% confidence interval for the mean number of unoccupied seats is given by [12.2; 13.1]. Find sample mean and sample standard deviation.
I've come up with the following equation, i know upto here it is right but i don't know how to solve it now.
x±1.96 s/ sqr100=12.2, 13.1
Please i'll be grateful if someone can help me ASAP !
Thank you
