hi everyone. I desperately need help in writing a hypothesis for a experiment im carrying out for my A-Level Psychology and stats. The title of the experiment is: An investigation to see if there is a difference between Type A and B personalities and their physiological response to a mildly stressful activity.

my Null hypothesis is: There will be no significant difference between the pulse rates of Type A and Type B personalities when undertaking a mildly stressful activity.

I just need a alternate hypothesis, any thoughts would be very much appreciative, I hate this module

Null: There is not a significant difference between the pulse rates of Type A and Type B personalities when undertaking a mildly stressful activity.
Alternate: There is a significant difference between the pulse rates of Type A and Type B personalities when undertaking a mildly stressful activity.

Or

Null: bpm(Type A) = bpm(Type A)
Alternate: bpm(Type A) =/= bpm(Type B)
