Testing a hypothesis is

State the hypotheses. Every hypothesis test requires the analyst to state a null hypothesis and an alternative hypothesis. Formulate an analysis plan. The analysis plan describes how to use sample data to accept or reject the null hypothesis. Analyze sample data. Interpret the results.

I got your back.        (#Answer)

1) The bottom wave has a greater

#frequency.

2)Which type of wave can carry energy through a vacuum?

#electromagnetic

3)The table shows information about two waves. Based on the given information, which conclusion can be made?

#Wave X has a greater amplitude.

4)A student drops a rock in a pond and notices that her reflection in the water becomes less clear. Which statement best explains the student’s #observation?

The water is not a smooth surface after the rock is dropped in the pond.

5) A room with which type of surface will most likely produce an echo?

#glass

6)A builder wants to make a room soundproof in a new home. The builder should use materials that .

#absorb sound waves and prevent echoes

7)A student puts a piece of black paper and a piece of white paper in the same sunny spot. After 30 minutes, she observes that the black paper feels warmer than the white paper. Which best explains the student’s observation?

#The black paper absorbs more waves from the sun than the white paper.

8)During a baseball game, the sound of the bat hitting the ball can be heard in most parts of the stadium. That sound is weaker at greater distances. What is the cause of this phenomenon?

#The sound waves are spread out over a large area.

9)Which type of wave can travel through a vacuum?

#light

10)AM waves have a wavelength of approximately 100 meters. FM waves have a wavelength of approximately 1 meter. Which one has a higher frequency? Which one has higher energy?

#FM has a higher frequency and higher energy.

11)Why would a person feel cooler wearing a white shirt rather than a black shirt on a sunny day?

#Light would be mostly reflected rather than absorbed or transmitted.
