*2.2.7 Analysis of results in relation to the copper content in the soil (mg/kg)*

Ho: There are no differences in Cu between sampling groups.

H1: There are differences in Cu between sampling groups.

In the ANOVA, the significance value is 0.317, a result that is obtained from comparing selected groups A, B, and C, respectively, in accordance with the heavy metal content of copper in the soil from granadilla fruit (*P. ligularis*) production fields according to intensity use of agrochemicals. Said value is greater than the significance of α = 0.05; therefore the statistical decision in this regard is to accept the null hypothesis; consequently, the alternative hypothesis is rejected, concluding that there is sufficient evidence to affirm that there are no significant differences in copper content in the soil samples at different intensity of application of agrochemicals at a confidence level of 95% (see **Table 7**).
