1. Below are the actual filling weights of 80 cans of peas (ounces). 15.83 15.39 15.93 15.98 15.98 15.85 16.00 15.98 16.04 15.79 16.01 15.91 16.21 15.89 15.77 16.05 15.77 15.96 15.75 16.37 16.24 15.71 15.84 16.09 15.75 16.38 16.43 16.49 16.60 16.63 16.42 16.01 16.17 15.91 16.13 15.82 15.91 16.27 15.92 15.92 15.33 15.90 16.01 16.08 15.57 16.12 16.11 16.81 16.65 16.68 15.44 15.51 15.92 15.72 16.25 15.90 15.53 16.00 16.29 15.69 16.88 16.10 16.20 15.94 15.93 15.73 16.47 16.07 16.00 16.53 16.31 15.62 15.81 15.99 16.40 15.84 15.95 16.19 15.74 15.90 a) Comment the efforts of two students from prior years of Research Methods and their decision to create a an absolute frequency distribution using the following arrangements: Arrangement 1 15.3 oz to under 15.5 oz 15.6 oz to under 15.8 oz 15.9 oz. to under 16.0 oz And so forth Arrangement 2 15.333 oz. to 15.555 oz. 15.555 oz. to 15.777 oz. 15.777 oz. to 15.999 oz. And so forth b) Making sure to avoid the above and other mistakes, design an absolute frequency distribution for the data above. Make sure to use Sturges' Rule, make uniform classes, and use round numbers for class boundaries. Consider that one thing you might want to know is how many cans are above or below the expected filling weight of 16 oz. e) Hand draw a histogram based on your work in b). How would you describe the shape of your histogram? Explain. d) Using your efforts from b) above, create a relative and cumulative frequency table. What does it tell you regarding the actual weight of cans relative to the expected weight of 16 oz.? Explain.Explanation / Answer
