For the datasets below, assume data was obtained via random sampling and that the population standard deviation is unknown. For the given variables of interest, Use R to create a normal probability plot and a histogram. Paste your work into your reportDescribe your findings. Do the graphs provide evidence against the assumption of a normally distributed population? Based on your descriptions (and the sample size n), determine if one mean inference is valid, and whether z-procedures or t-procedures should be employed.
