Hi, in this study, we want to answer the first question, we want to know if the results are statistically significant.
00:10
And with a significance level is 0 .05, we have the p value, it's less than the alpha level, so yes, it's significant.
00:24
Next, we want to know if...
00:27
So for the conclusion, we will reject the no hypothesis.
00:31
So the population means are not equal.
00:40
Next we're going to find what does this p value tell us? so it tells us that if the no hypothesis is true, there's only a 0 .01 chance of observing this sample, a sample this extreme, aka far away from the mean.
01:01
And next, we want to see it.

If type 2 error is possible so type 2 error is when we fail to reject h .o...
