Calculate the test statisticBiologists researching the effects of adding limestone sand as buffer for acid rain effects in streams monitored the pH levels of two streams each month for 36 months. The first stream had a mean pH level of 6.8 with a standard deviation of 2.3. The control stream...
Divide the total "D" by the "divisor" to find the t-value statistic for the dependent-samples t-test. TL;DR (Too Long; Didn't Read) Compare the obtained t-value statistic to the "critical t-value" found in your distribution t-table chart to determine whether you should reject the nu...
Question: Calculate the test statistic.F0= 5.84(Type an integer or decimal rounded to two decimal places as needed.)Identify the critical region for the current test. Select the correct choice below and fill in all answer boxes within your choice....
Calculate the test statistic and the p-value when {eq}\bar{x} {/eq} = 135, {eq}s {/eq} = 50, and {eq}n {/eq} = 100. Use a 5% significance level. {eq}H_0: \mu = 150 {/eq} {eq}H_1: \mu < 150 {/eq} Sample...

The z-test is theoretical in nature as the population standard deviation cannot be obtained easily. An easy alternative is to use the t-test statistic that uses the sample standard deviation that is easy to determine. However, the latter requires the satis...
The x axis in figure 1 doesn’t display the value of the test statistic (Z in this case) as would usually be the case. For clarity sake the concrete difference in conversion between the two landing pages has been displayed. So when in a split run test the alternative landing page return...
