The data set Health.csv data set uploaded in eLC. This data set contains a random sample of people and some of their health indicators measured a few years ago. The variable information is given below:

blood pressure (BP, in mm Hg) age (Age, in years) weight (Weight, in kg) body surface area (BSA, in sq. m) stress level (Low, Medium, High)

1. Write an R code to import this data in R as a tibble using the suitable function and store this data as newdata. Also, write an R code to make a subset of the data based on the low-stress level of the people and record it as Subdata. Print the first 3 observations of the Subdata.

2. Write an R code to compute the average weight of the people across the different levels of the variable stress level. Print the output.
