We know,
Mean = Total Sum / No. of Samples
Variance = Sum of Squares of Deviation from Mean / No. of
Samples
Standard Deviation = Square Root of Variance
Hence, the table follows :

Hence,
Mean and Standard Deviation of both diets are clearly different.
So, we can surely conclude that there is difference between two
diets.
