2. Make a data frame consisting of 20 and 10 columns. Eachcolumn j should consist of 20 values from a normal distributionwith mean (i-1) and standard deviation 0.5j. For example, the thirdcolumn should be normal(mean=2, sd=1.5). Using this data frame, doeach of the following (using code, of course):
a. Find the mean and standard deviation for each column.
b. Write code that counts the number of columns for which thesample mean and sample standard deviation are within 20% of thevalues used to generate the data.
c. Write code that writes the columns from part b to a new dataframe.
d. For each value in the new data frame, subtract its column meanand divide by the column standard deviation.
