. Please calculate the confidence interval based on the conditions below

Answers

Answer 1

With 90% confidence, we can say that the true population mean is between 11.448 miles and 12.552 miles.

How to explain the confidence interval

Confidence interval = sample mean ± margin of error

The margin of error is determined by the sample size, the standard deviation, and the level of confidence.

Standard error = population standard deviation / √sample size

Standard error = 3 / √80 ≈ 0.3354

Confidence interval = sample mean ± margin of error

Confidence interval = 12 ± 0.552

Confidence interval = (11.448, 12.552)

Therefore, with 90% confidence, we can say that the true population mean is between 11.448 miles and 12.552 miles.

The Sherburne formation is starting to become sandier the closer you get to the top because the shore is starting to transition to sandstone.

How did the distance to/from the shore change as Sherburne was deposited?

The Sherburne formation refers to sequence of sedimentary rocks that was deposited in the Late Cretaceous period in what is now Montana and Wyoming which is thought to have been deposited in a shallow marine environment with the shoreline fluctuating over time.

As the Sherburne was being deposited, the distance to/from the shore of the sea was changing in the area. At the bottom of the formation, the sediment is composed of finer-grained rocks such as shale and mudstone which indicate a more offshore environment.

But as you move up the formation, the sediment becomes coarser with the sandstone and conglomerate becoming more prevalent which suggests that the shoreline was moving closer and the area was becoming shallower.
