By using R language do the following for the following data : Question1 Part1 -Calculate the mean age for females and males and correlation coefficient between weights and lengths - Several types of correlation coefficients exist. Go to the help of the cor() function and find which correlation coefficient is calculated by default. -Add the appropriate argument to the cor() function in the previous command so that the Spearman correlation is calculated instead.

By using R language do the following for the following data :
Question1
Part1
-Calculate the mean age for females and males and correlation coefficient between weights and lengths
- Several types of correlation coefficients exist. Go to the help of the cor() function and find which correlation coefficient is calculated by default.
-Add the appropriate argument to the cor() function in the previous command so that the Spearman correlation is calculated instead.
Part2
-What is the maximum value of weight in the entire dataset?
- How many missing values are there for age?
- What is the mean value for BMIpre for the two surgical techniques (variable surgery)?
