Reference no: EM133239987

Using R Studio and the drivers.csv data:

1) Make a new object that consists of only drivers who were born in the 1980s (i.e., 1980 through 1989).

Hint, use filter().

Question: How many drivers were born in the 1980s?

2) Make a new object from drivers, that removes any driver whose first name contains the letter "o" or the letter "i" or the letter "e". Then, group by first name and count how many drivers have each of those remaining first names. Lastly, arrange this object in descending order for the number of occurrences for each name. Hint, use filter with grepl(); then, use group_by() and summarise() with n(); lastly, use
arrange() with desc().

Question: Which first name that is left is the most common?

It will not let me attach the drivers.csv data but here is section of it:
