But when you run a t-test you’re really only looking for two things: t-scores and alpha levels. Step 1: Compare the alpha level you chose (i.e. 0.05) to the p-value in the output. If the p-value in the output is smaller than the alpha level you chose, reject the null hypothesis. 1.Run StatPlus from the Applications Folder. 2.If you don’t already have Excel open, it will open it for you. 3.You will run the commands from the StatPlus menu (top menu bar). 4.Choose the appropriate cells from the Excel worksheet containing the data. 5.The results are printed to a separate Excel worksheet. The Elder Scrolls IV Oblivion Overview. The Elder Scrolls IV: Oblivion is the fourth installment of the series and one of the most known and loved fantasy RPG in gaming. Released in 2006 by Bethesda, the game is still very played to this day, and has a very active modding community, which is a testament of the life-span of a great game. The following content is included in the The Elder Scrolls IV: Oblivion® Game of the Year Edition Deluxe Fighter’s Stronghold Expansion Live the life of a noble warrior in this expansive castle with private quarters, grand dining hall, and a wine cellar.

The resulting data were: 170 167 174 179 179 187 179 183 179 156 163 156 187 156 167 156 174 170 183 179 174 179 170 159 187 The engineer hypothesized that the mean Brinell hardness of all such ductile iron pieces is greater than 170. Therefore, he was interested in testing the hypotheses: H 0: μ = 170 H A: μ > 170 The engineer entered his data into Minitab and requested that the 'one-sample t-test' be conducted for the above hypotheses. He obtained the following output. Descriptive Statistics N Mean StDev SE Mean 95% Lower Bound 25 172.52 10.31 2.06 168.99 $ mu$: mean of Brinelli Test Null hypothesis H₀: $ mu$ = 170 Alternative hypothesis H₁: $ mu$ > 170 T-Value P-Value 25 172.52 The output tells us that the average Brinell hardness of the n = 25 pieces of ductile iron was 172.52 with a standard deviation of 10.31. (The standard error of the mean 'SE Mean', calculated by dividing the standard deviation 10.31 by the square root of n = 25, is 2.06). The test statistic t* is 1.22, and the P-value is 0.117. ![]() If the engineer set his significance level α at 0.05 and used the critical value approach to conduct his hypothesis test, he would reject the null hypothesis if his test statistic t* were greater than 1.7109 (determined using statistical software or a t-table): Since the engineer's test statistic, t* = 1.22, is not greater than 1.7109, the engineer fails to reject the null hypothesis. That is, the test statistic does not fall in the 'critical region.' There is insufficient evidence, at the ( alpha ) = 0.05 level, to conclude that the mean Brinell hardness of all such ductile iron pieces is greater than 170. If the engineer used the P-value approach to conduct his hypothesis test, he would determine the area under a t n - 1 = t 24 curve and to the right of the test statistic t* = 1.22: In the output above, Minitab reports that the P-value is 0.117. Toshiba e studio 233 driver. Since the P-value, 0.117, is greater than ( alpha ) = 0.05, the engineer fails to reject the null hypothesis.
