I need the code in SAS and R and outputs please

2. The data below come from a study investigating a method of measuring body composition, and give the body fat percentage (% fat), age and sex for 18 adults aged between 23 and 61 years. Source: Mazess, R.B., Peppler, W.W., and Gibbons, M. (1984) Total body composition by dual-photon (153GD) absorptiometry. American Journal of Clinical Nutrition, 40, 834-839.

a Enter the data into SAS using a DATALINES statement in the DATA step. Use PROC PRINT to print the resulting data set. Report your output.

b Create a data frame in R for the body composition data (from part a). Print the data frame and report the output.

age % fat sex 23 9.5 male 23 27.9 female 27 7.8 male 27 17.8 male 39 31.4 female 41 25.9 female 45 27.4 male 49 25.2 female 50 31.1 female 53 34.7 female 53 42.0 female 54 29.1 female 56 32.5 female 57 30.3 female 58 33.0 female 58 33.8 female 60 41.1 female 61 34.5 female
