a.Bin the values ofx₁into 2 equal size groups. Label the groups with numbers 1 (lower values) and 2 (higher values). What is the average value ofx₁for group 1? (Hint: Sort the data by group number before calculating the average.)(Round your final answer to two decimal places.) b.Bin the values ofx₂into 3 equal interval groups. Label the groups with numbers 1 (lowest values) to 3 (highest values). How many observations are assigned to group 1? c.Bin the values ofx₃into the following two groups: 50 and > 50. Label the groups with numbers 1 (lower values) and 2 (higher values). How many observations are assigned to group 2?
