Weight of a rock: In a geology course, students are learning to use a balance scale to accurately weigh rocks. One student plans
vladimir2022 [97]

Answer:

We are 95% confident that the true weight of the rock is between 25.2 g and 29.1 g.

Step-by-step explanation:

Hello!

A geology student weighted a rock 5 times and estimated the average weight using a 95% CI [25.2; 29.1]gr

The confidence interval is used to estimate the value of the population mean, it gives you a range of values for it.

The 95% level of confidence of the interval indicates that if you were to construct 100 confidence intervals to estimate the population mean, you'd expect 95 of them to include the true value of the parameter.

So with a 95% confidence level, you'd expect the true average weight of the rock to be included in the interval  [25.2; 29.1]gr

I hope this helps!
