Question 6
A tube of toothpaste is required to be between 141.75 grams and 147.83 grams. We randomly sample 60 tubes of toothpaste from the first batch. From that sample taken, the average weight for the tube of toothpaste was 142.75 grams with a standard deviation of 1.57 grams.
By showing calculations:
Calculate and interpret the 95% and 99% confidence interval, given the above information.
Give a report and identify which range is larger?
Which interval, either 95th or 99th, falls within the specifications given?
Explain the relationship between standard deviation and the 95% and 99% confidence interval?
