Testing a hypothesis for two samples
Secret biological laboratory No. 42, commissioned by the Ministry of Defense, has developed two experimental species of large combat pigeons: VBG1 and VBG2. The appendix shows a sample of the combat part sizes for adult individuals of each species. The biological laboratory wants to find out whether the average combat part of the second species VBG is indeed greater than the combat part of the first species with a probability of more than 90%. Help the laboratory staff, namely:
- Formulate the null hypothesis.
- Formulate the alternative hypothesis.
- Calculate the mean for both samples.
- Calculate the standard deviation for both samples.
- Find the calculated value of the t-statistic for the difference of the samples.
- Make a comparison with the corresponding critical value of the t-statistic, -1.325.
- Draw a conclusion.
