Explanation / Answer

Sorted data is:

213 213 223 233 234 236 248 248 249 253 257 262 267 278 294 446

a. Mean = (213 + 213 + 223 + 233 + 234 + 236 + 248 + 248 + 249 + 253 + 257 + 262 + 267 + 278 + 294 + 446) / 16

= 259.6.

b. Median is the middle value i.e the average of 8th and 9th values

= (248 + 249) / 2 = 248.5.

c. Mode is the most repeating value. 213 and 248 repeat twice and they are therefore the modes.

Mode = 213, 248.

d. Minimum value = 213

Maximum value = 446

Midrange = (213 + 446) / 2

= 329.5.

Notice that 446 is quite large when compared to other values which are all in the range [213,294] and is therefore an outlier. Therefore, the correct answer is:

A. Yes, the time of 446 is very different from others.
