A high school student wants to find out how much screen time people spend on their phones. He does a random sample and finds the following data for screen time (in minutes):

195

250

180

175

120

60

300

210

193

135

200

265

Construct and interpret a 95% confidence interval for the mean amount of screen time people have on their phones.  Remember to check all necessary critera.

When discussing crime prevention part of the analysis of the reasons for crime are based on the economic and social inequities that are part of our society. It focuses on the root causes of crime; unemployment, racial discrimination, substandard housing, inadequate schools, inconsistent parenting.

There is a school of thought that states that Situational Crime Prevention deals only with the symptoms of crime, not the root causes, and is therefore inadequate as a means of crime prevention.

Is Situational Crime Prevention inadequate in its approach? Why or Why not?

Practice Using What You Have? Learned: Applying Constructivist Perspectives

Mr.? Swope's high school biology students are learning to use a dichotomous key to identify fish. As you observe his? teaching, think about his applications of constructivist principles.

Using what you know about constructivist? principles, explain why you think Mr. Swope asks students to work in groups as they learn to use the dichotomous key.

A recent study reported that 51​% of the children in a particular community were overweight or obese. Suppose a random sample of 500 public school children is taken from this community. Assume the sample was taken in such a way that the conditions for using the Central Limit Theorem are met. We are interested in finding the probability that the proportion of​ overweight/obese children in the sample will be greater than 0.47. Complete parts​ (a) and​ (b) below. . Calculate the probability that 47​% or more of the sample are overweight or obese.

The question in the textbook says:

"One study mentioned in an article that 90% of the students scored above the national average on standardized tests. Using your knowledge on mean, median and mode, explain why the school reports are incorrect. Does your analysis change if the term "average" refers to mean? To median? Explain what effect this misinformation might have on the perception of the nation's schools."

I really do not know how to answer this question, please help.
