The Motor Trend Car Road Tests dataset (mtcars.csv) contains the data extracted from the 1974 Motor Trend US magazine and comprises fuel consumption and 10 aspects of automobile design and performance for 32 automobiles (1973–74 models). The dataset contains 32 observations on 11 variables. Analyze the dataset according to the following steps:

1. Calculate sample mean and sample variance of each variable.

2. Calculate the sample variance-covariance matrix and the sample correlation matrix. What can you say about the variance-covariance matrix and correlation matrix? the file is in the link,
