Find the confidence interval (95%) on the average of the integrated EMG during each clench (25%, 50%,75%, and 100%) for all the subjects in your data set. Create a bar (horizontal) chart to represent this data with 25%, 50%, 75%, 100% groups as the dependent variable and average EMG as the independent variable. Include error bars that represent the 95% range on the EMG estimates. (This is an example of unnormalized data.)
