H1 : p value suggested (two-tail test) or p < value suggested or p > value suggested (one-tail test) Test statistic. z = where ps is the proportion in a sample of size n and q = 1 – p . Compare the test statistic with critical values of z. Critical values: Test type Significance level Critical values one-tail test …

To calculate a critical t value use the t-table with n-1 degrees of freedom (n-2 df for correlation test) and look in the column for α under Area in One Tail for a one-tail test or Area in Two Tails for a two-tailed test. Once you have your critical value compare it to your test statistic and follow the rule below: Reject H0 if the absolute ...

Look to the far left or the row, you’ll see the number 1.9 and look to the top of the column, you’ll see .06. Add them together to get 1.96. That’s the critical value! Note: The critical value is for two tail test and you are looking for both a left hand and a right hand tail, so don’t forget to add plus or minus! In our example you’d get

And then we find a t-critical value instead of a z-critical value. Example: Same example as above, doing a one-tail test. But this time, we don’t know the standard deviation is 2, and our sample size was only 17. Our sample standard deviation turns out to be 1.9, and we use this to find our t-score:

=NORMSINV(0.05)= critical value of -1.645. State your decision rule and draw a conclusion. Use tstatistic. when population variances are unknown and n< 30. Where: and compare it to tcritical = TINV( n1+n2-2)= the result will depend on the degree of freedom (n1+n2-2) Notice alpha is multiplied by 2 when performing a one-tail test.

L6_S19 One- and two-tail comparison. Here we have a comparison between a one-tail, and two-tail test, using the same alpha value. L6_S20 Questions. Having gone through this chapter and the previous 5, it’s a good point at which to stop and ask yourself whether you are comfortable with the work that has been covered so far.

If zsam (or tsam) ends up in this range, it’s a “more extreme” or “weirder” value than the critical z (or t) score, and so we reject the null hypothesis. In brief: For a lower tail test, the further your zsam or tsam is below 0, the weirder it is. For an upper tail test, the further your zsam or tsam is above zero, the weirder it is.
