Matlab question signal processing

Using the EMG file (EMG.txt) that was assigned. The sampling frequency is 1000Hz. Use MATLAB to create a subplot of the EMG signal graphed over time, and an amplitude spectrum of the EMG signal. a. What frequency has the largest power? b. In general, muscle fatigue is concentrated at lower frequencies (<50Hz). Comment on the muscle fatigue by calculating the % of power in 0-50Hz vs. the total frequency power spectrum. (<20% no fatigue; 20-40% mid; >40% high)
