The students calculate a chi-squared value of 92.86 and compare it with a critical value of 7.82. Which best completes the chi-square goodness-of-fit test?

The null hypothesis can be rejected, and student should conclude that the data may have resulted from genetic linkage

Explanation:

The correct option would be that the null hypothesis can be rejected, and the student should conclude that the data may have resulted from genetic linkage.

In a statistical test involving the goodness of fits, the calculated Chi-square value must be less than the critical value in order for the null hypothesis to be accepted. On the other hand, once the calculated Chi-square value is greater than the critical value, the null hypothesis is rejected.

In this case, the calculated value (92.86) is more than the critical value (7.82). Hence, the null hypothesis is rejected and the data can be concluded to be a deviation from the established standard.

sheep is a herbivore animal whereas grasshopper belongs to the class chordates but both of them feed on greens.  

if grasshopper and sheep feeding on a pasture land, i do not think both of them will have any impact on each other. however, the number of the species can make difference. since sheep feed on greens, there is a possibility there left no pasture land for the grasshoppers or they may get extinct.

the answer would be..
