Using two approaches, write the MATLAB code to compute the percentage of concussions overall (i.e., not classified by gender or sport) in the concuss.dat dataset. a. Approach 1: Use a loop to iterate over each data record, incrementing tallies as appropriate. b. Approach 2: Do NOT use a loop. Instead, index into your matrix to define the relevant vectors. Then use a logical mask to identify the subset of interest. For both approaches, use an fprintf statement to produce this output: Overall, 0.074 6% of the athletes sustained concussions. Notes: Be sure to load the data file into memory (once is sufficient). You may NOT use MATLAB's sum function in Approach 1. To produce the % sign in fprintf, use %%. Do NOT hard-code the 0.0746!! Comments are NOT required. As a reminder, here are the first few records (rows) contained in the concuss.dat file. The columns, in order, represent sport, gender, year, concussion and count
