Answer:

-20n/3n

Step-by-step explanation:

-4       1

---   /    ---

9n       15n

Keep, change, flip

- Keep the -4/9n

- Change the division sign to a multiplication sign

- Flip the 1/15n to 15n/1

-4       15n

---   *    ---

9n       1

Cross simplify.

9n divided by 3 is 3n.

15n divided by 3 is 5n.

-4       5n

---   *    ---

3n       1

-4 times 5n equals -20n

3n times 1 equals 3n

-20n

Researchers investigated the possible beneficial effect on heart health of drinking black tea and whether adding milk to the tea
Elanso [62]

Answer:

(a)  It is an experiment.

(b) Group III has been tested to compare the effect of tea

Step-by-step explanation:

24 volunteers are randomly selected to one of the three groups.

Group I drinks two cups of hot black tea without milk

Group II drinks two cups of hot black tea with milk

Group III drinks two cups of hot water but no tea.

At the end of the month, the researchers measured the change in each of the participant's heart health.

The average change of health status of three Groups can be measured and let it be X1', X2' and X3'. We can set up the hypothesis of no difference of heart health i.e H0 : µ1 = µ2 = µ3 against the alternative hypothesis that they are not equal. As the sample size is less than 30, we can use t-statistic.

Under the above logic, (a) it is an experiment.

(b) Group III has been tested to compare the effect of tea or to have comparison between GroupI and Group III.
