Question

Nambe Mills manufactures a line of metal tableware called "Nambeware." A piece of Nambeware is produced by sand casting a special alloy of several metals. After casting, the piece goes through a series of steps, including shaping, grinding, buffing, and polishing The top and bottom portions of the data set that Nambe Mills collected for a study of its production schedule are reproduced below; dots indicate that the intervening rows in the data set are not displayed. (Source: DASL [The Data and Story Library]) Piece ID Type Diameter (Inches) Polishing Time (Minutes) 47.65 63.13 58.76 34.88 55.53 Price (Dollars) 144 215 105 69 134 14 8 10 56 57 58 59 20.85 26.25 21.87 23.88 16.66 24.50 52 62.50 89 21.50 15 Note that the variable Type has five different values, which are coded as 1 and 5 -plate bowl, 2-casserole, 3-dish, 4-tray, Complete the table below to indicate the number of elements, variables, observations, and data values that are included in the complete data set. Data Set Term Elements Variables Observations Measurements How Many? Which variables in the data set are quantitative? O Type, Diameter, Polishing Time, and Price O Polishing Time and Price O Diameter, Polishing Time, and Price Diameter and Price

Answer 1

from above number of elements =59

number of variables =4 (type,diameter, polishing times , Price)

observations =59 (number of set of measurements)

measurements =59*4 =236

which variables are the data set are quantitative = Diameter, polishing time and Price
