Question

question 22 solve the problem. the manager of a car dealership records the colors of automobiles on a used car lot. identify the type of data collected. qualitative quantitative use the following to answer the question. 88 56 98 72 55 78 64 87 92 73 47 32 76 78 94 96 89 90 33 67 92 87 compute the frequency for the seventh bin. (use 10 - point bin) (choose a smaller number to start to create the first bin lower limit) 22 5 7 6

Explanation:

Step1: Identify data type

Colors are non - numerical and descriptive, so they are qualitative data.

Step2: For frequency calculation

First, we need to order the data set: 32, 33, 47, 55, 56, 64, 72, 73, 76, 78, 78, 87, 87, 88, 90, 92, 92, 94, 96, 98. Using 10 - point bins, assume the first bin is 30 - 39. We count the number of data points in each bin. To find the lower limit for the seventh bin, if the first bin lower limit is 30 and bin width is 10, the lower limit of the seventh bin is \(30+(6\times10)=90\). We then count the number of values in the 90 - 99 bin. There are 4 values (90, 92, 92, 94, 96, 98), so the frequency for the seventh bin is 5.

Answer:

Question 22: qualitative
Frequency for seventh bin: 5
