Name: Confidence Interval for a Population Mean, Standard Deviation Unknown, Student-T (modifed R. Bloom)
ID: m18935
Language: English (en)
Summary: This module explains how to construct a confidence interval estimate for an unknown population mean when the population standard deviation is unknown, using the Student-t distribution. This module has been revised from the original module m16959 by S. Dean and Dr. B. Illowsky in the textbook collection Collaborative Statistics to include step by step solutions for all examples.
