Probability and Statisticsb
Hello, can a get a paragraph given another example like (or contradicting) the following and an explanation of how it can be use in business.

"One of the hypothesis you can give for a test is the null hypothesis. This theory is looked at as the status quo; you can assume that whatever you are researching has no effect. The other is the alternative hypothesis. This theory is the one in which we say that our test will have an effect or result.

For example; we are testing out a drug on a group of individuals and we are injecting 100 people with a dose of this drug. We know that the mean response time for people not injected with any drug is 1.2 seconds and the mean of the 100-injected individual's response time is 1.05 seconds with a standard deviation of 0.5 seconds. One of our hypothesis (the null) is saying that the drug is not going to have any effect on our individuals; it's not going to work. Our second hypothesis (the alternative) is the assumption that our drug will have some effect on the test panel of people".
