A study looked at whether a brief diet intervention might improve depression symptoms. In the study, 75 college-age students with elevated depression symptoms and relatively poor diet habits were randomly assigned to either a healthy diet group or a control group. Depression levels were measured at the beginning of the experiment and then again three weeks later. The response variable is the reduction in depression level (as measured by the researchers) at the end of the study. Larger numbers mean more improvement in depression symptoms.   The average change in the healthy diet group was 7.87 units. The average change in the control group was 0.76 units.  Suppose the p-value was 0.321. Give the conclusion of the test .  Assume an alpha value of 0.05.

True or False:  The p-value is a measure of agreement between the null hypothesis and our data.

Suppose you are on a spaceship flying toward at 0.4c, where c is the speed of light. You shine a beam of light toward Earth. How fast does the beam strike Earth’s surface?

What predictions were made by the Big Bang hypothesis that were later observed and confirmed? Choose all that apply.

True or false: If I plan to perform a double slit experiment on 1 million electrons, it is possible to predict where most of the electrons will land.

A positively charged particle in the nucleus of an atom is a [pr]. A particle of light is a [ph].
