The actual t-test results are found in theOne-Sample Testtable. - Thetvalue and its degrees of freedom (df) are not immediately interesting but we'll need them for reporting later on. The p value, denoted by “Sig. (2-tailed)” is .02; if the population mean is exactly 400 grams,...
Given tt and dfdf, we can simply look up that the 2-tailed significance level pp = 0.73 in this Googlesheet, partly shown below. Interpretation As a rule of thumb, we reject the null hypothesis if p < 0.05. We just found that p = 0.73 so we don't reject our null hypothesis: given...
set up the Null and Alternative Hypothesis in such way that, when we do our t-test, we can choose to do one tailed test. According to this article, onetailed tests are more powerful than two-tailed test. In addition to that, this videois also quite helpful understanding these topics...
Release factor variant strains were challenged with µ phage to assess phage infectivity with genes terminating with TAA and TGA only. Data are mean ± 95% confidence interval forn = 3 biological replicates. Unpairedt-test for comparison withE. coliMG1655. NS, not significant; ND, no...
Null Hypothesis: H0: μ = μ0, where μ0 is some number Alternative Hypothesis: two tailed 实例: one tailed 实例: 评判标准: Type I and Type II Errors: Significance Level 所以需要balancing In otherwords, if we do not reject the null hypothesis, we conclude only that the data do notprovi...

Statistical analyses were conducted using R version 3.6.3, Python version 3.7, and GraphPad Prism 8.0. Continuous variables were presented as mean ± standard deviation, while categorical variables were expressed as counts and percentages. Baseline data were compared using the t-test for continuou...
T-tests were two-tailed. All other tests were one-tailed. The R and Python code used in this analysis are available at a public repository at https://github.com/owenn wl/CUCOVID19_DXLPA. Data availability Requests for data should be directed to the ...
