Does it take less time for seeds to germinate if they are near rock music that is continuously playing compared to being near classical music? The 57 seeds that were exposed to rock music took an average of 27 days to germinate. The standard deviation was 8 days. The 57 seeds that were exposed to classical music took an average of 31 days to germinate. The standard deviation for these seeds was 12 days. What can be concluded at the a= 0.05 level of significance? a. For this study, we should use Select an answer b. The null and alternative hypotheses would be: Ho: Select an answer H₁: Select an answer Select an answer ✓ Select an answer Select an answer Select an answer c. The test statistic?✓ = d.
