Test: TEST-1 Submit Test This Question: 1 pt 6 of 16 (0 complete) This Test: 16 pts possible Find the (a) mean, (b) median, (c) mode, and (d) midrange for the given sample data. An experiment was conducted to determine whether a deficiency of carbon dioxide in the soil affects the phenotype of peas. Listed below are the phenotype codes where 1 = smooth-yellow, 2= smooth green. 3-wrinkled-yellow, and 4 wrinkled-green. Do the results make sense? (a) The mean phenotype code is (Round to the nearest tenth as needed.) (b) The median phenotype code is Type an integer or a decimal.) (c) Select the correct choice below and fill in any answer boxes within your choice O A. The mode phenotype code is (Use a comma to separate answers as needed.) 0 B. There is no mode (d) The midrange of the phenotype codes is (Type an integer or a decimal.) Do the measures of center make sense? 0 A. Only the mean, median, and mode make sense since the data is numerical 0 B. All the measures of center make sense since the data is numerical. O C. Onlv the mode makes sense since the data is nominal.

Explanation / Answer

A) mean = (1+2+2+4+3+3+4+4+3+2+4+3+4)/13 = 3

B) data in ascending order,

1,2,2,2,3,3,3,3,4,4,4,4,4

Median = middle most value = 3

C) Option-A) the mode is 4
