Question

A beverage company plans to use a mean chart to monitor liquid beverage weights in 500-ml bottles. If bottle weight is normally distributed with a mean of 500 ml and a standard deviation of 6 ml, what is the sampling strategy?

A) Measure samples of 30 bottles hourly and record the mean weight.
B) Measure samples of 500 bottles monthly and record the mean weight.
C) Measure samples of 30 bottles daily and record the mean weight.
D) Measure samples of 500 bottles annually and record the mean weight.

Answer 1

The beverage company should measure samples of 30 bottles daily and record the mean weight to monitor liquid beverage weights in 500-ml bottles.

Step-by-step explanation:

The sampling strategy that the beverage company should use to monitor the liquid beverage weights in 500-ml bottles is option C) Measure samples of 30 bottles daily and record the mean weight.

This sampling strategy involves measuring a sample of 30 bottles every day and recording the mean weight. By regularly measuring samples, the company can monitor the variation in bottle weights and detect any deviations from the mean weight of 500 ml.

Sampling daily also allows for quick identification of any issues with the bottling process and prompt corrective action, ensuring the quality and consistency of the beverage.
