Jeffrey, as an eight-year old, established a mean time of 16.43 seconds for swimming the 25-yard freestyle, with a standard deviation of 0.8 seconds.His dad, Frank, thought that Jeffrey could swim the 25-yard freestyle faster using goggles. Frank bought Jeffrey a new pair of expensive goggles and timed Jeffrey for 15 25-yard freestyle swims.For the 15 swims, Jeffrey's mean time was 16 seconds.
An alternative hypothesis (denoted Ha), which is the opposite of what is stated in the null hypothesis, is then defined. The hypothesis-testing procedure involves using sample data to determine whether or not H0 can be rejected. If H0 is rejected, the statistical conclusion is that the alternative hypothesis Ha is true.
Hypothesis testing is explained here in simple steps and with very easy to understand examples. Hypothesis testing is the fundamental and the most important concept of statistics used in Six Sigma and data analysis. Also explained is the p-Value and how to interpret it.
