Question

Describe how you could use hypothesis testing to help make a decision in getting your son to sleep by 9 pm please help

Answer 1

Ans) In hypothesis testing, analysts test a sample with the objective of accepting or rejecting a null hypothesis (this hypothesis is presumed to be true unless it is proved false) and hence tells the analyst if the hypothesis is true or not. Steps involved in hypothesis testing are÷

1. Choose two hypothesis so that one can proved to be wrong.
2. Formulate the plan that how to analyze the data.
3. Carry out plan and analyse the result.
4. Analyse the result and choose one hypothesis to be true and other to be false.

Now let us use the hypothesis in the question ÷

Step 1- Yes make him sleep at 9pm otherwise he will be late for school the next day because he will not be able to get up early and will also be lazy all day.

No, 9pm is too early and he can sleep by 10pm and will still be able to wake up on time. (Null hypothesis)

Step 2÷ I will check the hypothesis by observing waking pattern of the kid and analysing if he is able to wake up at the right time by sleeping at 10pm or not.

Step 3÷ The kid is not able to wake up by 6am and gets late for school because small kids need atleast 9hr sleep and also the kid was dull whole day.

Step 4÷ My null hypothesis is wrong and consequently, the other hypothesis i.e. make him sleep at 9pm otherwise he will be lazy all day is proved right.
