Hey if you like my answer please give me the brainliest answer :)
Ok so we have a ratio of 1:3 here. (1 is for the hour of tv and 3 is for hours of homework)
3 can go into 15 (hours of homework last week) 5 times. That means we must multiply 3 by 5 to get 15 so that we can fit the ratio to last week. Because we did that, we have to multiply 1 by 5 as well.
1 × 5 = 5 hours of homework!
Answer:
In order to be a linear function, a graph must be both linear (a straight line) and a function (matching each x-value to only one y-value)

Step-by-step explanation:
Answer: See explanation
Step-by-step explanation:
1. Use the five steps of hypothesis testing.
Step 1: The aim of the research is to conduct the five steps of hypothesis testing.
Step 2:
Null hypothesis: H0 u= 4
Population mean: H1 u = 4
Alternate hypothesis: u ≠ 4
Population mean: u ≠ 4
Step 3 and step 4 are attached.
Step 5: Based on the calculation, the calculated value of t is less than the t critical value, therefore, the null hypothesis will be failed to be rejected.
2. Sketch the distributions involved
This has been attached.
3. Explain the logic of what you did to a person who is familiar with hypothesis testing, but knows nothing about t tests of any kind.
The distribution is "t".
The means is tested by using T-test.
Chi-square is used to test the single variance.
