Using MatLab:

Consider the following data points:

155,142,149,130,151,163,151,142,156,133,138,161,128,144,172,137,151,166,147,163,145,116,136,158,114,165,169,145,150,150,150,158,151,145,152,140,170,129,

188,156

a. Construct a frequency distribution with eight classes. Begin with a lower class limit 110, and use a class width of 10

b. Use the results from part a to construct a histogram for these data sets

c. Use classes in part a to find mean

d. Use classes in part a to find standard deviation

e. Draw a box plot for the given data
