327, Chi-square test
The hypothesis, in this case, is H 0 : the two samples are independent, versus, H a1 : the two
sample are dependent.

a. 6 cells (66.7%) have expected count less than 5. The
minimum expected count is 1.02.
The chi-square critical value at (0.05, 4) = 9.488, the null hypothesis is rejected. Thus, the two
samples are dependent.

343, Nonparametric procedures
The Mann-Whitney U-test results are as summarized in Table 1 and Table 2. In this case, the
null hypothesis to be tested is H 0 : The two samples come from the same distribution, versus,
H a1 : the two sample do not come from the same distribution.

a. The p-value is 0.048 since p-value is smaller than the level of significance the null
hypothesis is rejected. Thus, the sample population is distinct.
b. Z value corrected for ties is -1.974

The p-value of t-test (assuming the data has equal variance) is 0.37, whereas that of Mann-
Whitney U test is 0.048. In t-test, the hypothesis to be tested is H 0 : The two samples have an
equal mean, versus, the H a1 : the two sample population have different mean.

At 95% level of significant, these results are not statistically significance, since p-value 0.280
is greater than α = 0.05

1. The results of Kruskal-Wallis and One-way ANOVA results indicate that there is no
statistically significant difference between the mean of the variables.
