Recent research suggests that college students spend an average of about 1.5 hours on social media each day. Suppose a DVC school newspaper reporter believes that DVC students spend less time than that on social media each day. After obtaining a sample of DVC students, the reporter finds that DVC students spend an average of 1.3 hours each day on social media.
1. As the reporter sets up a hypothesis test to determine if their belief is correct, what is their claim?

In this example, the researcher's claim would be something like:

"I believe that DVC students spend less than 1.5 hours on social media each day."

When conducting research, you need to be clear on what your claim is going to be. A claim is a statement that summarizes your opinion. It also provides the main idea that the rest of your essay should try to address. If your research is pursued with rigour and perseverance, you would most likely be able to prove your claim in the end.

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47
