(i) Determine the mean, the median, the mode, and the range for the above data.
(ii) Compute the first and the third quartiles
(iii) Compute the z-scores for the months of may.

i have attempted this but, i'm not sure if i'm doing it right

The months are merely the periods. You could view the months as the x values, and the numerical data as the y values, and generate a plot.
