Mathematics

ExtremeBDS [4]3 years ago

"Porportional Relationships" means that the rate in which it increases is the same.

For example: 1, 3, 5, 7, 9 is a porportional relationship, because it increases each time by (+2).

Now, look at the first one.

From y to x, y being 2, x being 10, you divided 5 from x to get 2. Next, you divided 6 from 30 to get 5. Because the number dividing is different, it is not proportional

NOT PROPORTIONAL

Look at the second one.

From y to x, y being 12, x being 10, you divided 1.2

Now, look at the next one. 30/25 = 1.2

Finally, the last one. 48/40 = 1.2

Because all of them are 1.2, the answer is proportional

PROPORTIONAL

Nataliya [291]

Step-by-step explanation:

A study was to be undertaken to determine if a particular training program would improve physical fitness. A sample of 31 university students was selected to be enrolled in the fitness program. The researchers wished to determine if there was evidence that their sample of students differed from the general population of untrained subjects. The sample mean is 47.4 and a standard deviation of 5.3. The 98% confidence interval is determined and is given as, (45.2, 49.6) .

If the level of confidence is changed to 95%, then the confidence interval will become shorter but the p-value will not change because it is calculated using the test statistic. So the correct answer is (a).
