Question: Using your sample problem. Suppose we rejected the null. That means with yellow background, people spend time that is not equal to 20 minutes. How will I know if they spend more time or less time? Thank you!

Can this really follow a normal distribution? The amount of time spent on the website can theoretically approach someone’s entire lifetime in minutes, while it cannot go below zero (you cannot spend negative time on the website) Hence, skewness >0, and does not follow normal distribution..?

OMG you are good. I hope I can do good in The SAT math 2 test

I dont understand if the probability of getting the mean as 30 min is very low or equal to threshold then it means that probability of getting mean value of 20 min is high so why reject null. I believe its the opposite of what you said. We accept alternative only when the probability of getting mean as 30 min is high. Please explain if i am incorrect.
