Question

A researcher is looking to compare the caloric intake of students who report high levels of stress vs those who report low levels of stress. Write the null and alternative hypotheses.

Answer 1

Null hypothesis(NH): Everything equal, the caloric intake does not cause difference in the stress levels of those with high levels of stress (HS)and those experience low levels of stress(L.S)

NH: HS= L.S=/ 0 ( read the ‘=/‘ as not equal to zero sign )

Alternative hypothesis: 1) The caloric intake proportionally increases the difference between individuals with high levels of stress and those with low levels of stress.

2) The caloric intake proportionally decreases the difference between individuals with high levels of stress and those with low levels of stress.

AH: HS>L.S=0 or HS< L.S=0
