Use Excel and the data set below AND ATTACHED FILES Each column of data contains a sample from the same population. For each column compute the mean and standard deviation. Then, compute the mean of the five numbers in each line (i.e. row) of data, creating a sixth column, and calculate the mean and standard deviation of this column of means.

1) Construct a frequency histogram of each of the six columns (use 10 bins in each and label the axes and bins appropriately). After editing, copy the histograms and paste (as pictures; jpg, pdf, etc.) onto a single regular-size page in MS Word, resizing the figures as necessary.

2) In Excel, compute the mean and standard deviation for each of the six columns. On a new (second) page in your Word document, paste the table below and fill in the missing cells:
