I don't understand how to approach these 5, the z score charts are for the one where it says use table

Find the standard deviation for the following group of data items. A set of data items is normally distributed with a mean of 900 and a standard deviation of 20. Find the data item in this distribution that corresponds to the given z-score. 22, 26, 26, 33 =1.5 The standard deviation is approximately 4.57. The data item that cor onds to z = 1.5 is 930. (Type an integer or a decimal.) (Round to two decimal places as needed.) Use the display of data to find the mean, median, mode, and midrange.
