Homework: HW 2 Score: 0 of 1 pt 3.2.33 Save 17 of 41 (24 complete) Hw Score: 56.56%, 23.19 of 41 pts Question Help A certain group of test subjects had pulse rates with a mean of 82.5 beats per minute and a standard deviation of 12.2 beats per minute. Use the range rule of thumb to identify the limits separating values that are significantly low or significantly high. Is a pulse rate of 76.9 beats per minute significantly low or significantly high? Significantly low values arebeats per minute or lower. Type an integer or a decimal. Do not round.)

Explanation / Answer

1) = 82.5

= 12.2

Siginificantly low value = - 2* = 82.5 - 2 * 12.2 = 58.1

Significantly low values are 58.1 beats per minute.

No,76.9 is not significantly low.

2) y = 8.14 - 0.33 * x

x = 6

y = 8.14 - 0.33 * x = 8.14 - 0.33 * 6 = 6.16 = 6.2
