An article reported the following data on oxidation-induction time (min) for various commercial oils:
| 85 | 104 | 130 | 160 | 180 | 195 | 135 | 145 | 215 | 105 | 145 |
| 151 | 152 | 135 | 87 | 99 | 92 | 119 | 129 |
a) Calculate the sample variance and standard deviation. (Round your answers to three decimal places.)
s2 = min2
s = min
(b) If the observations were reexpressed in hours, what would be the resulting values of the sample variance and sample standard deviation? Answer without actually performing the reexpression. (Round your answer to three decimal places.)
s2 = hr2
s = hr

A physiological experiment was concluded to study the effect of
various factors on a pulse rate. The participants took their own
pulse. They then were asked to flip a coin. If their coin came up
head, they were to run in place for 1 minute. Then everyone took
their own pulse again. The dataset pulse.txt, available from
Moodle, contains the following variables: ROW- id numbers, from 1
to 92; PULSE1- first pulse rate; PULSE2- second pulse rate;
