Does it take more time for seeds to germinate if they are near rock music to being near classical music? The 48 seeds that were exposed to rock music took an average of 25 days to germinate. The standard deviation was 7 days. The 41 seeds that were exposed to classical music took an average of 20 days to germinate. The standard deviation for these seeds was 15 days. What can be concluded at 0.01 level of significance? the a = a. For this study, we should use Select an answer b. The null and alternative hypotheses would be: Ho: Select an answer v ? Select an answer v (please enter a decimal) H1: Select an answer v ? Select an answer (Please enter a decimal) c. The test statistic (please show your answer to 3 decimal places.)

Does it take more time for seeds to germinate if they are near rock music that is continuously playing compared
to being near classical music? The 48 seeds that were exposed to rock music took an average of 25 days to
germinate. The standard deviation was 7 days. The 41 seeds that were exposed to classical music took an
average of 20 days to germinate. The standard deviation for these seeds was 15 days. What can be concluded at
the a = 0.01 level of significance?
a. For this study, we should use Select an answer
b. The null and alternative hypotheses would be:
Họ: Select an answer v ?
Select an answer v (please enter a decimal)
H1: Select an answer v
Select an answer v (Please enter a decimal)
c. The test statistic ? v =
(please show your answer to 3 decimal places.)
d. The p-value =
(Please show your answer to 4 decimal places.)
e. The p-value is ? a
f. Based on this, we should Select an answer v the null hypothesis.
g. Thus, the final conclusion is that ...
O The results are statistically insignificant at a = 0.01, so there is insufficient evidence to conclude
that the population mean time for seeds exposed to rock music to germinate is more than the
population mean time for seeds exposed to classical music to germinate.
O The results are statistically significant at a = 0.01, so there is sufficient evidence to conclude that
the mean germination time for the 48 seeds exposed to rock music that were observed is more than
the mean germination time for the 41 seeds that were exposed to classical music that were observed.
O The results are statistically significant at a = 0.01, so there is sufficient evidence to conclude that
the population mean time for seeds exposed to rock music to germinate is more than the population
mean time for seeds exposed to classical music to germinate.
O The results are statistically insignificant at a = 0.01, 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.
