How do you write an alternative hypothesis example?
The alternate hypothesis is just an alternative to the null. For example, if your null is “I’m going to win up to $1000” then your alternate is “I’m going to win more than $1000.” Basically, you’re looking at whether there’s enough change (with the alternate hypothesis) to be able to reject the null hypothesis.

What is a comparison hypothesis?
Comparing two proportions (e.g., comparing two means) is common. A hypothesis test can help determine if a difference in the estimated proportions reflects a difference in the population proportions. The difference of two proportions follows an approximate normal distribution.
