Q 3

Step-by-Step Solution:

Step 1 of 1

For a set of data, a number for which 75% of the data is less than that number. The third quartile is the same as the median of the part of the data which is greater than the median. Same as 75th percentile. It is denoted by

 1 110 2 120 3 178 4 213 5 234 6 234 7 235 8 237 9 240 10 243 11 245 12 245 13 250 14 250 15 251 16 252 17 254 18 255 19 255 20 259 21 260 22 266 23 269 24 273

=

= 18.75

Here, 18.75th observation lies in between 18th and 19th value in the ordered group.

Now, 18th value = 255

19th value = 255

Thus, = 18th value + 0.75(19th value - 18th value)

= 255 + 0.75(255 - 255)

= 255 sec
