WebQuestion. Use the Shapiro-Wilk test to check the normality assumption for the variable Starting_Sal. According to this test, does the variable Starting_Sal meet the normality assumption? p-value = 2.856e-15. Yes, because the P-value of the Shapiro test is less than 0.05. Yes, because the P-value of the Shapiro test is greater than 0.05. WebThe normal probability plot was designed specifically to test for the assumption of normality.

The null hypothesis for the Shapiro-Wilk test is that a variable is normally distributed in some population. A different way to say the same is that a variable’s values are a simple random sample from a normal distribution. As a rule of thumb, we reject the null hypothesis if p < 0.05. googles social responibility programs
