A soft drink manufacturer labels its sport drink as containing 600 milliliters per bottle. They want to ensure variations in temperature, human error, and other factors are not causing the volume of liquid per bottle to be significantly higher or lower than this advertised amount. They conduct a random sample of 64 bottles and find they contain an average of 611 milliliters with a standard deviation of 30 milliliters. Conduct a hypothesis test with a 2% significance level to determine if sport drink bottles are being filled correctly.
