many students brag that they have more than 100 friends on a social media platform. for a class project, a group of students asked a random sample of 13 students at their college who used the social media platform about their number of friends and got the data available below. is there strong evidence that the mean number of friends for the student population at the college who use the social media platform is larger than 100? use the inference for a population mean web app to complete parts a through d below. be sure to use the data in this exercise and not the pre - loaded data when using the web app.\n\nclick the icon to view the data about the numbers of friends.\n\na. identify the relevant variable and parameter.\nwhat is the relevant variable?\na. the number of students that use the social media platform\nb. the mean number of students at the college that use the social media platform\nc. the proportion of students at the college who use the social media platform that have more than 100 friends\nd. the mean number of friends that students have on the social media platform\ne. the number of friends that students have on the social media platform\n\nwhat is the parameter?\na. the number of friends for students at the college who use the social media platform\nb. the mean number of friends for people who use the social media platform\nc. the mean number of friends for students at the college who use the social media website\nd. the proportion of students at the college who use the social media platform that have more than 100 friends\ne. the proportion of students at the college that use the social media platform\nb. state the null and alternative hypotheses.\n$h_0:mu$ \n$h_a:mu$ \n(type integers or decimals. do not round.)

Answer

Brief Explanations:

a. The relevant variable is what is being measured for each individual in the study. Here, it's the number of friends students have on the social - media platform. The parameter is a characteristic of the population. In this case, it's the mean number of friends for students at the college who use the social - media platform. b. The null hypothesis ($H_0$) is a statement of no effect or no difference. The alternative hypothesis ($H_a$) is what we are trying to find evidence for. Since we want to test if the mean number of friends is more than 100, the null hypothesis is that the mean is equal to 100 and the alternative is that the mean is greater than 100.

Answer:

a. Relevant variable: D. The mean number of friends that students have on the social media platform Parameter: C. The mean number of friends for students at the college who use the social media website b. $H_0:\mu = 100$ $H_a:\mu>100$
