Ivanshal [37]

Answer:

Product A performed better in the study because only 30% failed to get relief with this product, whereas 39% failed to get relief with Product B.

Step-by-step explanation:

Sample A = 20 people

Experienced relief in A = 14 people

Sample B = 100 people

Experienced relief in B = 61 people

The percentages of people who failed to get relief with each product are defined as follows:

F_A = (1-\frac{14}{20})*100\%\\ F_A=30\%\\\\F_B = (1-\frac{61}{100})*100\%\\ F_B=39\%

Therefore, Product A performed better in the study because only 30% failed to get relief with this product, whereas 39% failed to get relief with Product B.

Leokris [45]

Answer:

C. 210

Step-by-step explanation:

Plugging it in directly

30/14=2.14 (not an integer)

210/6=35

210/10=21

210/14=15

all of the above result in integers, so the answer is C.

D is not even checked because it is larger than 210
