To inspect manufacturing processes, companies typically examine samples of parts for deficiencies. One company that manufactures ballpoint pens selected samples of its manufactured pens on each of 8 days. The company recorded, for each sample, the number of defective pens in the sample. Here are their data. 24, 21, 10, 28, 11,9, 8, 23 Send data to calculator Send data to Excel (a) What is the mean of this data set? If your answer is not an integer, round your answer to one decimal place. (b) What is the median of this data set? If your answer is not an integer, round your answer to one decimal place. O zero modes (c) How many modes does the data set have, and what are their values? Indicate the number of modes by clicking in the appropriate circle, and then indicate the value(s) of the mode(s), if applicable. O one mode: O two modes: and
