A student was asked to find a 95% confidence interval for weight of their backpacks in pounds using data from a random sample of size n = 20. Which of the following is a correct interpretation of the interval 3.6 < μ < 14.4? Assume the population is normally distributed.
There is a 95% chance that the weight is between 3.6 and 14.4.
With 95% confidence, the weight of a randomly selected backpack will be between 3.6 and 14.4 pounds.
With 95% confidence, the mean weight of all backpacks is between 3.6 and 14.4 pounds.
There is a 95% chance that the mean of a sample of 20 backpacks will weigh between 3.6 and 14.4 pounds.
The sample mean weight of all backpacks is between 3.6 and 14.4 pounds, 95% of the time. We know this is true because the mean of our sample is between 3.6 and 14.4.
