Greetings!

I have this sampling problem where i am given the population of 1545 vehicles and their age. Without any further info apart from 95% CI I am being asked to find the sampling error and sample size. How is this possible?

Thank you!

Even then, nobody knows the sampling error.

alpha is the allowed sampling error/P accepting Ha when Ho is true; but nobody knows THE sampling error. Just lke we never know mu.

Translation:

1) FILE EXPLANATIONS "Case Study 2020" This file contains the prices of nine (9) variables for a population of 1545 vehicles used for long-distance international passenger transport for a specific year in a European country. (The excel file with the data)

2) (1) Assuming that it performs a simple random sampling: (a) Determine the magnitude of the sampling error. (b) Determine the required sample size that ensures the desired degree of accuracy, at a 95% confidence level.

I too think it is impossible, but thats what the problem asks!
