population mean = 41.17 ; mean of sample means = 41.14
population standard deviation = 15.60 ; standard deviation of sample means = 4.26
a) From the above information , comment the result of :
i) population mean and mean of sample means;
ii) population standard deviation and standard deviation of sample means
i) population mean and mean of sample means
The means of sample mean is always equal to the population mean
Here also,
population mean = 41.17 ; mean of sample means = 41.14
ii) population standard deviation and standard deviation of sample means
The standard deviation of sample means is less than that of population standard deviation as
population standard deviation = 15.60 ; standard deviation of sample means = 4.26
