6. Interpret the effect of hand soap on microbial diversity from your analysis (Was hand soap effective at controlling microbial diversity?). Draw a bar graph of the means and be sure to record the numerical value of the mean for the microbial diversity before and after treatment above the bar graph. Also on the graph, record the p-value from your analysis and place numbers on the scale bar of the y-axis (for the mean of the class's microbial diversity for the before and after treatment groups). Based on the interpretation of your data, was hand soap effective at controlling microbial diversity? hand soap hos Pvalve P 20.0009 Means it has an effect at Controlling Microbial diversity How does your analysis of the p-value and means allow you to make this interpretation?
