Question

How do I get calculate the class, frequency and midpoint to make a histogram for the distribution of this data?

Each time I tried to put in the data it does not come out correctly. I need assistance. Is the normality assumption that was made at the beginning valid? Why or why not? Hint: Does this distribution have the properties of a normal distribution as described in the course textbook? Real data sets are never perfect; however, it should be close. One option would be to construct a histogram like you did in Project 1 to see if it has the right shape. Something in the range of 10 to 12 classes is a good number. The max is 1268.33 and min is 913.81. I just can’t seem to get this one.
