Write 3 paragraph summary about hypothesis

State the hypotheses. We begin by stating the value of a population mean

in a null hypothesis, which we presume is true. For the children watching TV

example, we state the null hypothesis that children in the United States watch an

average of 3 hours of TV per week. This is a starting point so that we can decide

whether this is likely to be true, similar to the presumption of innocence in a

courtroom. When a defendant is on trial, the jury starts by assuming that the

defendant is innocent. The basis of the decision is to determine whether this

assumption is true. Likewise, in hypothesis testing, we start by assuming that the

hypothesis or claim we are testing is true. This is stated in the null hypothesis. The

basis of the decision is to determine whether this assumption is likely to be true.Keep in mind that the only reason we are testing the null hypothesis is because

we think it is wrong. We state what we think is wrong about the null hypothesis in

an alternative hypothesis. For the children watching TV example, we may have

reason to believe that children watch more than (>) or less than (<) 3 hours of TV

per week. When we are uncertain of the direction, we can state that the value in the

null hypothesis is not equal to (≠) 3 hours.

In a courtroom, since the defendant is assumed to be innocent (this is the null

hypothesis so to speak), the burden is on a prosecutor to conduct a trial to show

evidence that the defendant is not innocent. In a similar way, we assume the null

hypothesis is true, placing the burden on the researcher to conduct a study to show

evidence that the null hypothesis is unlikely to be true. Regardless, we always make

a decision about the null hypothesis

explanation:

there is 2 main differences, basically which are the users and the market. the other difference is the kind of content

people who use tik tok are mainly people from east asia, kind of like the app douyin. musically, on the other hand, are used by people from america or european countries.

while tik tok videos show things like daily life videos, comedy, or just funny videos, musically are like people mimicking songs with their own actions, 'imitate' singers and video clips.

hope this !
