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?

Select an answer the null hypothesis.
O The results are statistically significant at x = 0.05, so there is sufficient evidence to conclude
that the population mean time for seeds exposed to rock music to germinate is less than the
population mean time for seeds exposed to classical music to germinate.
The results are statistically significant at a = 0.05, so there is sufficient evidence to conclude
that the mean germination time for the 57 seeds exposed to rock music that were observed is
less than the mean germination time for the 57 seeds that were exposed to classical music that
were observed.
The results are statistically insignificant at a = 0.05, so there is statistically significant
evidence to conclude that the population mean time for seeds exposed to rock music to
germinate is equal to the population mean time for seeds exposed to classical music to
germinate.
O The results are statistically insignificant at cx = 0.05, so there is insufficient evidence to
conclude that the population mean time for seeds exposed to rock music to germinate is less
than the population mean time for seeds exposed to classical music to germinate.
