The mean pulse rate (beats per minute) of a random sample of 40 males was 67.3 bpm. For a random sampl of 40 females the mean was 77.5 bpm. The population standard deviation for males is 10.3 bpm and 11.6 bpm for females. Using the P-Value method and test the claim that there is a difference in mean pulse rates. Use alpha = 0.03.

Question

The mean pulse rate (beats per minute) of a random sample of 40 males was 67.3 bpm. For a random sampl
of 40 females the mean was 77.5 bpm. The population standard deviation for males is 10.3 bpm and 11.6
bpm for females.
Using the P-Value method and test the claim that there is a difference in mean pulse rates. Use alpha = 0.03.
Step 5:
There is enough evidence to reject the claim that there is a difference in pulse
rates for males and females.
O There is enough evidence to support the claim that there is a difference in pulse
rates for males and females.
There is not enough evidence to reject the claim that there is a difference in
pulse rates for males and females.
There is not enough evidence to support the claim that there is a difference in
pulse rates for males and females.
