Does it take a different amount of time for seeds to germinate if they are near rock music that is continuously playing compared to being near classical music? The 54 seeds that were exposed to rock music took an average of 23 days to germinate. The standard deviation was 11 days. The 54 seeds that were exposed to classical music took an average of 17 days to germinate. The standard deviation for these seeds was 12 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: Ho: Select an answer V Select an answer V Select an answer v(please enter a decimal) H: Select an answer Select an answer vSelect an answer v (Please enter a decimal) c.

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
different 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 54 seeds exposed to rock music that were observed is
different than the mean germination time for the 54 seeds that were exposed to classical
music that were observed.
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.
O The results are statistically significant at a = 0.01, so thére is sufficient evidence to conclude
that the population mean time for seeds exposed to rock music to germinate is different than
the population mean time for seeds exposed to classical music to germinate.
h. Interpret the p-value in the context of the study.
OIf the sample mean germination time for the 54 seeds exposed to rock music is the same as the
sample mean germination time for the 54 seeds exposed to classical music and if another 54
seeds exposed to rock music and 54 seeds exposed to classical music are observed then there
would be a 0.78% chance of concluding that the mean germination time for the 54 seeds
exposed to rock music differs by at least 6 days from the mean germination time for the 54
seeds exposed to classical music
O There is a 0.78% chance that the mean germination time for the 54 seeds exposed to rock
music differs by at least 6 days from the mean germination time for the 54 seeds exposed to
classical music.
OThere is à 0.78% chance of a Type I error.
OIf the population mean time for seeds exposed to rock music to gérminate is the same as the
population mean time for seeds exposed to classical music to germinate and if another 54
seeds exposed to rock music and 54 seeds exposed to classical music are observed then there
would be a 0.78% chance that the mean germination time for the 54 seeds exposed to rock
music would differ from the mean germination time for the 54 seeds exposed to classical music
by at least 6 days.
1. Interpret the level of significance in the context of the study.
OThere is a 1% chance that there is a difference in the population mean time for seeds exposed
to rock vs. classical music to germinate.
OIf the population mean time for seeds exposed to rock music to germinate is the same as the
population mean time for seeds exposed to classical music to germinate and if another 54
seeds exposed to rock music and 54 eeds exposed to classical music are observed, then there
