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 above

Three-circle, red-on-white is one distinctive pattern painted on ceramic vessels of the Anasazi period found at an archaeological site. At one excavation, a sample of 179 potsherds indicated that 62 were of the three-circle, red-on-white pattern. (a) Find a point estimate p̂ for the proportion of all ceramic potsherds at this site that are of the three-circle, red-on-white pattern. (Round your answer to four decimal places.)
The durability of a plastic product is directly affected by the hardness of the plastic types used. 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.
