Plastic hardness which is measured with the Durometer Hardness test goes between 0 and 100. A higher number represents a harder plastic. A comparative test is conducted to investigate the quality of the plastic based on their hardness from 3 different factory sources. The test is conducted with 6 different plastic types acquired from each factory source. The types of plastic are sorted based on the nature of hardness in ascending order.
- Cumulative information can be portrayed using a graph called an ogive . To construct an ogive, we first make a table that displays cumulative frequencies and cumulative relative frequencies. A cumulative frequency is obtained by summing the frequencies of all classes representing values less than a specified lower class limit (or cutpoint). A cumulative relative frequency is found by dividing the corresponding cumulative frequency by the total number of observations. From the cumulative frequency a graph called ogive can be constructed in this manner: In an ogive, a point is plotted above each lower class limit (or cutpoint) at a height equal to the cumulative relative frequency. Then the points are connected with lines Find the cumulative frequency and relative cumulative frequency and construct the Ogive for each of the following cases: Days to maturity of 40 investments Residential Energy Consumption Survey: Consumption and Expenditures example aboveYour hypothesis test for a proportion has a right-tailed critical region. The test statistic is zz = 1.84. Find the p-value accurate to 2 decimal places..59. Potatoes. A high-quality product is one that is consistent and has very little variability in its characteristics. Controlling variability can be more difficult with agricultural products than with those that are manufactured. The following table gives the weights, in ounces, of the 25 potatoes sold in a 10-pound bag. (a) Summarize the data graphically and numerically. Give reasons for the methods you chose to use in your summaries. (b) Do you think that your numerical summaries do an effective job of describing these data? Why or why not? (c) There appear to be two distinct clusters of weights for these potatoes. Divide the sample into two subsamples based on the clustering. Give the mean and standard deviation for each subsample. Do you think that this way of summarizing these data is better than a numerical summary that uses all the data as a single sample? Give a reason for your answer.
