Update: The data is below, the question is not incomplete. I just need an understanding of the R script formula to use to get to the right answer.

Use R Script in R studio to complete the following exercise and provide

The question below uses the pollution data set, which can be called by using avgpm25csv file. It includes data on daily pollution level (PM 2.5) which are available from the U.S. EPA web site. The variables are: pm25: Pollution level, fips: county code, region, longitude, latitude.

Construct two subsets of data, one that contains all observations of west region, second that contains all observations in east region. Assuming variances are not equal, run an independent samples t-test to check the equality of means of pollution level by using first 134 observations of each subset. Report the p value of the t-testand comment on its meaning.
