(b) Write a proposal and submit it to your instructor for approval. In the proposal, discuss the aims of your project and how you plan to gather the data to make your sample unbiased.

(c) After your proposal has been approved, gather 50 pieces of data by the method you proposed. 

(d) Rank the data from smallest to largest. 

(e) Compute the mean, median, mode, and midrange of the data.

(f) Determine the range and standard deviation of the data. You may round the mean to the nearest tenth when computing the standard deviation.

(g) Construct a frequency distribution, histogram, frequency polygon, and stem-and-leaf display of your data. Select your first class so that there will be between 5 and 12 classes. Be sure to label your histogram and frequency polygon.

(h) Does your distribution appear to be normal? Explain your answer. Does it appear to be another type of distribution discussed? Explain.

(i) Determine whether your distribution is approximately normal.
