Question

Filling cola bottles Bottles of a popular cola are supposed to contain $300$ milliliters (ml) of cola. There is some variation from bottle to bottle because the filling machinery is not perfectly precise. From experience, the distribution of the contents is approximately Normal. An inspector measures the contents of six randomly selected bottles from a single day’s production. The results are $299.4 297.7 301.0 298.9 300.2 297.0$

Step-by-Step Solution

Answer

No, it is not possible to deduce that the average amount of cola in a bottle is less than 300 ml.

Step 1 ; Given information

Given in the que $p$

$$\begin{gathered} t=\frac{\overline{x}-\mu }{\frac{s}{\sqrt{n}}} \\ =\frac{10-5}{\frac{12}{54}} \\ =90 \end{gathered}$$
