Answer:
B.
Step-by-step explanation:
The sample size taken for the school is too small.
5 people not being vegetarian does not mean NO OTHER students are vegetarian also. Thus, an assumption based on this probability of 5 people would not be correct unless fully supported. This makes option A wrong.
Answer B is correct because with small numbers, probability varies a lot and may change drastically with the addition of data.
For example: the 6th person we sample says he/she is a vegetarian.
This would change the probability drastically to 1/6 = 0.1667
Because this is a drastic change, and fluctuation is clear, answer B is correct.
C is wrong because probability is not subjective.
Answer: D. Chloe did not cut enough fabric because she only cut the amount of extra fabric.
Step-by-step explanation:
From the question, we are informed that a direction on a sewing pattern say to cut an extra 15% of fabric to account for error and that Chloe needs 0.75 yard of fabric to make a skirt.
Based on the information given in the question, the extra fabric will be:
= 15% × 0.75
= 15/100 × 0.75
= 0.15 × 0.75
= 0.1125
Therefore, the correct amount of fabric to cut will then be the amount of yard needed for the skirt plus the extra. This will be:
= 0.75 + 0.1125
= 0.8625 yards
Based on the above calculation, Chloe did not cut the correct amount of fabric as she only cut the amount of extra fabric.
