Comparing the population mean to a target with a 1-Sample t-test
We will use the 1-Sample t-test to investigate the population mean for measures of the economy. The data here is for the UK Gross Domestic Product (GDP). This is often used as a measure of the health of an economy. We will test to see if the percentage growth of GDP per quarter for the UK is equal to zero.
