1)

H0 : i.e there is no difference in commute times for male and females working San Francisco residents

H1 : i.e there is significant difference in commute times for male and females working San Francisco residents

(i) Response Variable = Commute Time

(ii) Explanatory variable = Gender

(iii) Observational study : Here we are basically studying/observing the time taken for commuting for males and females in San Francisco area.

Let me know in comments if anything is not clear. Will reply ASAP. Please do upvote if satisfied.

We can setup null and alternative hypotheses for decision making. Remember in hypothesis testing the "equals" part will be with the null hypothesis, so you can have less than or equal to, greater than or equal to, or just equal to when defining the null hypothesis. The alternative hypothesis will be, then, either greater than, less than, or not equal to in relation to the above null criteria. See below for how it looks symbolically for the three possible setups....

Share with your peers the null and alternative hypotheses for a decision that is relevant to your personal or professional life (any example is fine). Remember in hypothesis testing the "equals" part corresponds to the null hypothesis, so you can have less than or equal to, greater than or equal to, or just equal to when defining the null hypothesis. The alternative hypothesis will then be either greater than, less than, or not equal to in relation to the above...
