You read a report that claims that 78% of community college students use social networking sites. You assume this is also true at Valencia College. To check that assumption you select a random sample of 60 Valencia College students and ask if they use social networking sites. If many samples of size 60 wer collected from this population and what you assumed were true, label the sketch of the p-hat sampling distribution below with the mean (rounded to two

You read a report that claims that 78% of community college students use social networking sites. You assume this is also true at Valencia

College. To check that assumption you select a random sample of 60 Valencia College students and ask if they use social networking sites.

Are the criteria for using the normal distribution met? In the space provided, state all three conditions and explain how you verify

You read a report that claims that 78% of community college stdents use social networking sites. You assume this is also true at Valencia

College. To check that assumption you select a random sample of 60 Valencia College students and ask if they use social networking sites,

If many samples of size 60 were collected from this population and what you assumed were true, what would be the mean of the p-hat

sampling distribution? Give your answer as a decimal rounded to two decimal places.
