Problem 17BSC

Step1 of 3:

We have the following duration times (seconds) of 24 eruptions of the Old Faithful geyser in Yellowstone National Park. The duration times are sorted from lowest to highest.

 x 110 120 178 213 234 234 235 237 240 243 245 245 250 250 251 252 254 255 255 259 260 266 269 273

Step2 of 3:

We need to Find the percentile corresponding to the given time. 213 sec.

Step3 of 3:

The given data in ascending order

 x 110 120 178 213 234 234 235 237 240 243 245 245 250 250 251 252 254 255 255 259 260 266 269 273

The percentile for 213 sec. is

=

= 12.5
