Your statistics instructor claims that 60 percent of the students who take her Elementary Statistics class go through life feeling more enriched. For some reason that she can't quite figure out, most people don't believe her. You decide to check this out on your own. You randomly survey 64 of her past Elementary Statistics students and find that 33 feel more enriched as a result of her class. Now, what do you think? Conduct a hypothesis test at the 5% level. Note: If you are using a Student's t-distribution for the problem, you may assume that the underlying population is normally distributed. (In general, you must first prove that assumption, though.) O Part (a) O Part (b) O Part (c) O Part (d) O Part (e) O Part (f) O Part (g) O Part (h) O Part (i) Construct a 95% confidence interval for the true proportion. Sketch the graph of the situation. Label the point estimate and the lower and upper bounds of the confidence interval. (Round your answers to four decimal places.)

The population of Lindersburg in the state of Awesomeness has been rapidly increasing. The population started with 100 people and has been tripling every 4 months. Write an equation and create a graph to model this scenario.

Please Help. I'm really stuck.   The problem gives me this graph, and ask me to find if this graph has interquartile range greater 6.0.   I know how to find interquartile range, but that is only when there is a specific numbers given. This graph only shows if numbers are between something to something. Like 0 ~ 9.   Please help, I have no idea.

How is the graph y=(x-4)^2+1 shifted relative to the graph y=x^2
