Zebra 5/7 × 21 = 15

The juice label (300ml) is in the confidence interval.

So, the 95% CI does not give the inspector the reason to believe the amount of juice differs from 300ml

Step-by-step explanation:

Given

From the 95% confidence interval value, we have: 296.4 to 300.2

Within this interval, we can find the juice label 300

i.e. 296.4 < 300 < 300.2

In other words, the juice label (300ml) is in the confidence interval.

So, the 95% CI does not give the inspector any reason to believe the amount of juice differs from 300ml.
