In testing the hypotheses: $H _ { 0 } : \mu = 25$ $H _ { 1 } : \mu \neq 25$ ,
a random sample of 36 observations was drawn from a normal population. The sample standard deviation is 10 and the sample mean is 22.8.
Can we conclude at the 5% significance level that the population mean is not significantly different to
25?
