The correct answer is a) Dr. Wong could publish his data in a scientific journal and have different investigators try to reproduce his results. This is due to external validity, when data from a research can be confirm and reproduced, after selecting a proper sample size and determine alfa and beta power, for the study. If no bias exists, other researchers should be able to replicate and validate Dr’s Wong Results.
B and C options are both unacceptable due to ethical issues, and D is incorrect based on the central limit theorem; if Dr’s Wong sample is at least 30 in number (for each group: A=test group and B=control group) the statistical inferences can be translated into larger populations. Smaller samples than this, are not recommended due to bias and internal validity.

<h3 /><h3>How has Western Europe been impacted by water proximity?</h3>
The climate is cooler and there is more rain thanks to the ocean winds bringing moisture. People also settled near the coast and in cities along rivers.
This led to a culture of people who sailed a lot and explored many parts of the world. The economy is also reliant on trade thanks to the ease of transportation provided by the proximity to water.

Answer:
speed = distance/time
distance= 10km
time= 1 hour 30 mins = 1.5 hour
speed = 10/ 1.5 = 6.66666666667 km/h
hope this answer helps you.....
