2. The application claims that 30% (0.30) of the MEs are pop music. Helena does50 trials in which she selects 100 MEs at random. She determines that 25 outof every 100 MEs are pop music, with a standard deviation among the trials ofabout 5 MEs. Does Helena's research provide strong evidence that the socialmedia app's claim of 30% pop music MEs is false? Explain. Helena gathers data about the music preferences of users of a social mediaapplication. She gathers information on music events (MEs). In her study, amusic 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 arehip hop/rap. Juan wants more proof of her claim.• Juan uses technology to determine the genres of music of 100 MEs hechooses at random. He determines that 9 were hip hop/rap.• Juan points out the 9% rate to Helena.Part AAssume Helena is correct and 15% of MEs on the app are hip hop/rap.Use random numbers and a simulated sampling distribution to simulate theoutcome of several trials, in which each trial samples 100 MEs from the appand counts the number of hip hop/rap MEs. Make a histogram for your data.Is the model consistent with what you would expect? Explain.

A researcher is curious to see if the amount of time spent on social media influences how often friends meet in person to socialize. After their sample is selected the researcher asks the subjects on average how much time they spend on social media each day and then asks their subjects to keep track of how many times they meet in person with their friends to socialize and report back at the end of the month. What type of study design is this? The research obtains 100 participates who met with their friends in person at least 15 times in the last month to socialize and 100 participates who met with their friends in persons less than 15 times in the last month to socialize. Then the researcher asks the participants on average how many hours per day did they spend on social media during the month before. What type of study design is this? Options for both questions: Cohort, case-control, cross-sectional, clinical trial

Suppose Laura, a facilities manager at a health and wellness company, wants to estimate the difference in the average amount of time that men and women spend at the company's fitness centers each week. Laura randomly selects 15 adult male fitness center members from the membership database and then selects 15 adult female members from the database. Laura gathers data from the past month containing logged time at the fitness center for these members. She plans to use the data to estimate the difference in the time men and women spend per week at the fitness center. The sample statistics are summarized in the table.

It’s assumed that students need to stay awake more to study during finals week. One way to measure this is how much coffee is consumed during Finals week at night. A local coffee house near APU counted the number of cups of coffee sold per hour during Finals week after 6 p.m. We randomly select ten (10) hours of sales records during Finals week and find out that the following number of cups of coffee were consumed: 18, 17, 22, 14, 17, 20, 22, 24, 15, 15 By comparison, the sales records from a previous week were used as a comparison.
