Since the sample size is quite large then according to the central limit theorem, the sample mean is approximately normally distributed.
The sample mean would be the same as the population mean that is
The sample standard deviation is given by
Where 
is the population standard deviation and n is the sample size.
Therefore, the required parameters are:
