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 47 seeds that were exposed to rock music took an average of 15.6 days to germinate. The standard deviation was 3.7 days. The 60 seeds that were exposed to classical music took an average of 14.8 days to germinate. The standard deviation for these seeds was 4.1 days. What can be concluded at the 0.10 level of significance?
Continuous Probability Distributions
Probability distributions are of two types, which are continuous probability distributions and discrete probability distributions. A continuous probability distribution contains an infinite number of values. For example, if time is infinite: you could count from 0 to a trillion seconds, billion seconds, so on indefinitely. A discrete probability distribution consists of only a countable set of possible values.
Normal Distribution
Suppose we had to design a bathroom weighing scale, how would we decide what should be the range of the weighing machine? Would we take the highest recorded human weight in history and use that as the upper limit for our weighing scale? This may not be a great idea as the sensitivity of the scale would get reduced if the range is too large. At the same time, if we keep the upper limit too low, it may not be usable for a large percentage of the population!

Conclusion: There is [ Select]
evidence to make the conclusion that there is a
seeds exposed to rock music have an average germination time that is less than seeds exposed to
classical music.
p-Value Interpretation: If the mean time to germinate is the same for seeds exposed to rock and
classical music and if another study was done with a new randomly selected collection of 47 seeds
exposed to rock music and 60 seeds exposed to classical music, then there is a
[ Select ]
percent chance that for these new samples the seeds exposed to
rock music would germinate an average of at least [Select]
days later than
the seeds exposed to classical music.
Level of significance interpretation: If the mean time to germinate is the same for seeds exposed to
rock and classical music and if many more studies are done with randomly selected collection of 47
seeds exposed to rock music and 60 seeds exposed to classical music each then

v percent of these studies would result in the false conclusion that the
mean number of days to germinate for the seeds exposed to rock music is greater than the mean
number of days to germinate for the seeds exposed to classical music.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F69ffb34c-ff2c-4107-815b-4535fc837ae3%2F4abdf6d2-4612-4c5b-8fea-b2e965f877c5%2F4hwan8t_processed.jpeg&w=3840&q=75)
