Explain.

Using the Student Survey data, the following bar chart plot involves the variable IDEOLOGY (How would you rate yourself politically?). Chose the following statement(s) that is/are TRUE. Note, there many be more than one correct answer multiple statements that are true.

The following pie chart is from the Student Survey displaying the variable SPORTS (What type of sport do you currently watch the most?). Chose the following statement(s) that is/are TRUE. Note, there many be more than one correct answer multiple statements that are true.

Using the histogram, list three specific and distinct pieces of information about this distribution (not the histogram – i.e the class width). Be sure you have a statement about the shape, a statement about the center, and a statement about the spread for this distribution. Please write in full sentences.

What is the role of the radiofrequency excitation pulse in MRI?

The center point inside the bore of the scanner, and also the center point of the 3 gradient coils is called __________________________________.
