NB: If the standardized value of the mean is less than -1.65 we reject/refuse the null hypothesis (H0) and accept the alternative Hypothesis (H1) however if the standardized value of the mean is more than -1.65 we accept/allow the null hypothesis and reject/refuse the alternative hypothesis.

The above drawing of graph and level of significance are applicable while the sample mean is < or like that is less than the population mean,The given is utilized when sample mean > population mean

NB: If the samples mean standardized value < 1.65, we accept the null hypothesis however reject the alternative. If the sample means value > 1.65 we reject/refuse the null hypothesis and accept the alternative hypothesis .The above drawing is normally utilized when the sample mean described is greater than the population mean

NB: if the standardized value of the sample mean is with -2.58 and +2.58 accept the null hypothesis otherwise reject it and then accept the alternative hypothesis
