Expert Solution

Solution:

To test the normality of the data i have performed Kolmogorov-Smirnov test for Normality using SPSS software and provided results below. It would be more appropriate for review.

Test result:

Null hypothesis: Data follows normal distribution

Alternative hypothesis: Data do not follow normal distribution.

Conclusion: From the table, we can see P-value is less than significance level 0.05 we reject null hypothesis of normality and conclude that data is not normal.

Consider the following Boxplot of given data to get clear idea of spread of the data.

Conclusion: We can see from the above boxplot the box is not symmetrical with the mean and median in the center therefore, we can conclude that data do not meets the assumption of normality.
