ABSTRACT

The one-sample t-test is applied to test for a population mean. It compares the mean score of a sample ( x ¯ ) https://s3-euw1-ap-pe-df-pch-content-public-u.s3.eu-west-1.amazonaws.com/9780429023309/58a45e90-6c22-48ce-9f7d-1612419219fa/content/eq84.tif"/> to an unknown value (μ0). The unknown value is a population mean. That is, H 0 : μ = μ 0   against   H 1 : μ ≠ μ 0 https://s3-euw1-ap-pe-df-pch-content-public-u.s3.eu-west-1.amazonaws.com/9780429023309/58a45e90-6c22-48ce-9f7d-1612419219fa/content/eq85.tif"/>
