Webwhen n (sample size) is greater or equal to 30, can we use use z statistics because the sampling distribution of the sample mean is approximately normal, right? if this is the case, then why does t table contain rows where the degree of freedom is 100, 1000 etc (i.e. degree of freedom = n - 1)? if n is greater or equal to 30, we would be using a z table anyway, so is … WebApr 16, 2024 · We now determine what the p-value is for this hypothesis test. We look at the value of the test statistic, and where this is located on a t-distribution with 19 degrees of freedom. For this distribution, we have 4.2 x 10-7 as our p-value. (One way to determine this is to use the T.DIST.RT function in Excel.) WebApr 1, 2024 · Simulating a one-sample t-test.
