Not yet. I'm trying to compute the test statistic value for the population mean. I'm a bit stuck and could use some help. Can you help me with these?
There are two girls who's doing their set work on statistic. And Samantha is having a hard time on how to compute the test static value. And her friend (Shane) ask her what's the problem and try to help her.
Hey, are you done working on the set work that ma'am Rosalie gave us?
Yes, that's correct. I have collected a sample from a population, and i want to determine if the sample mean is significantly different from the hypothesized population mean.
Shane starts to help her friend and discuss about the problem.
Yeah, I'd be happy to assist you. So, just to clarify, are you trying to perform a hypothesis test for the population mean?
Okay, I understand that part. But how do I compute the actual test statistic value?
And now, Shane was explaining to Samantha.
Great. The first step is to define your null and alternative hypothesis. The null hypothesis, denoted as H₀, typically states that the sample mean is equal to the hypothesized population mean. The alternative hypothesis, denoted as H₁, would be that the sample mean is not equal to the hypothesized population mean.
