Helena tells Juan that even though he found a rate of 9% hip hop/rap MEs, this doesn't contradict her assessment that 15% of MEs as a whole are hip hop/rap. Juan's result could be due to natural variability. Use your sampling distribution from Part A to find a range of values centered on the mean that includes 95% of the samples. Use this to determine whether Juan's result contradicts Helena's assessment.

![Helena gathers data about the music preferences of users of a social media
application. She gathers information on music events (MEs). In her study, a
music event is defined as a posting that has a hashtag or is linked to other video-
sharing websites.
1. From her data, Helena claims that about 15% of MEs on the application are
hip hop/rap. Juan wants more proof of her claim.
• Juan uses technology to determine the genres of music of 100 MEs he
chooses at random. He determines that 9 were hip hop/rap.
• Juan points out the 9% rate to Helena.
Part A
Assume Helena is correct and 15% of MEs on the app are hip hop/rap.
Use random numbers and a simulated sampling distribution to simulate the
outcome of several trials, in which each trial samples 100 MEs from the app
and counts the number of hip hop/rap MEs. Make a histogram for your data.
Is the model consistent with what you would expect? Explain.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F3b8f79a9-b6a4-48ca-ab39-5a4f4172185c%2F48ab4a0b-cc45-4eb4-8a89-7b7700c14656%2Fk0j5xya_processed.jpeg&w=3840&q=75)
