A hypothesis will be used to test that a population mean equals 5 against the alternative that the population mean is less than 5 with unknown standard deviation. What is the critical value for the test statistic T0 with alpha 0.01 and n=23. (use 3 decimal places)

Solutions

Expert Solution

We have here,

Left tailed test,

Degree of freedom =n-1=23-1=22

t critical value for left tailed test = -2.508
