We are interested in studying whether Private Colleges costs at least $15,000 more than Public Colleges. This is to run an advertisement campaign to promote more high school students to consider public colleges to save at least $15,000 in tuition a year. See the excel file CollegeCosts for the random samples showing the annual cost of attending private and public colleges. Data are in thousands of dollars.

What is the p-value for this hypothesis testing. ROUND TO 4 DECIMAL PLACES. Thank you!

To test whether extracurricular activity is a good predictor of college success, a college administrator records whether students participated in extracurricular activities during high school and their subsequent college freshman GPA.

In the diffraction lab, we will use a laser which has wavelength is 650 nm and aim it at the hair until a clear diffraction pattern is visible on the screen or wall.

1. Does fine or coarse hair result in a greater distance between fringes in the resultant diffraction pattern? Explain the reasoning for your response.

2. Explain why laser light is used for this lab activity.

3. Differentiate between interference and diffraction and provide a common example of each from your home, work, or school experiences.

The economy is experiencing a short-run recession (low levels of output and high rates of unemployment). You are the chief economic advisor of the federal government. In each of the following two cases, propose a concrete example of policy that the government can implement to boost the economy. Be specific on how each policy would affect output, unemployment, and price level using the AD-AS model.

1. Assume that you are from the Keynesian (mainstream) school of thought.

Question 22:

You previously used R to generate a contingency table for the association between bullying (anyB, i.e., at school or online) and indications of suicide risk (anyS). The table was generated as follows:

> table(anyB,anyS)

anyS

anyB 0 1

   0 649 108

   1 165 78

1. Use these data to compute the odds ratio for the crude association between bullying and indications of suicide risk. (2 points)
2. Interpret the odds ratio that you calculate in a sentence. (2 points)
