Extract of sample "Hypothesis Testing & Variance"

Hypothesis Testing & VarianceIntroduction.A two tailed test of hypothesis at 5 percent significant level (μ = .05) is equal to inquiring whether the 95% interval of confidence for the means takes into consideration the hypothesized mean. Whenever the confidence interval includes the mean that is hypothesized an alternate or null hypothesis could be formulated. This implies that the null hypothesis cannot be ignored. This paper explores the t-tests and z-tests.Test 1.Hypothesis Test 1 looking at intrinsic satisfaction by Gender.
