Answer:
a) 0.251
b) 0.483
c) 0.0994
Step-by-step explanation:
We are given the following information:
We treat adult adults trusting national newspapers to present the news fairly and accurately as a success.
P(Adult trust) = 60% = 0.6
Then the number of adults follows a binomial distribution, where
where n is the total number of observations, x is the number of success, p is the probability of success.
Now, we are given n = 9
a) exactly five
b) at least six
We have to evaluate
c) less than four
We have to evaluate
That question is accompanied by these answer choices:
<span>A. The scale is accurate but not precise.
B. The scale is precise but not accurate.
C. The scale is neither precise nor accurate.
D. The scale is both accurate and precise.
Then you need to distinguish between accuracy and precision.
Accuracy refers to the closeness of the measure to the real value, while precision, in this case, refers to the level of significant figures that the sacle report.
The fact that the scale reports the number with 4 significant figures means that it is very precise, but the fact that the result is not so close to the real value as the number of significan figures pretend to be, means that the scale is not accurate.
So, the answer is that the scale is precise but not accurate (the option B).
