Answer:

By looking at a fossil record, a scientist can learn how a species developed over time. These fossils show what a species looked like in the past. Through testing, they can determine how old and what kind of organism it was so they can compare it to similar organism today to see how it evolved.

Hope this helps! :D

Answer:

You could use the fossil record to help explain the evolution of a species by watching how it aged, what it ate, how it breed and where it lived along with a million of other things. It could have lived in the 20 below freezing and then you find that same fossil in the warmest place in the world it shows that the species either adapted or possibly had an offspring that could handle the high temperatures.

a researcher wishes to know whether there is a significant difference in the number of knee injuries reported among four sports.
boyakko [2]

Answer:

Chi-square analysis cannot be used to check for significant difference in the number of knee injuries among four sports.

Explanation:

The chi-square analysis is a statistical procedure that is used to test association between measured variables or goodness of fits of a set of measured variables to expected outcomes.

<em>In the case of testing for significant difference, chi-square analysis cannot be used as testing for significant difference in two or more means requires using t-test, analysis of variance, or any other relevant statistical procedure.</em>

To compare number of knee injuries reported among four sports for significant difference, the most suitable statistical procedure would be analysis of variance.
