Question

In two to three complete sentences, explain in detail how you might use Terri Vogel’s data to answer the following question. "Does Terri Vogel drive faster in races than she does in practices?"

a) Analyze race and practice speeds separately and compare the averages.
b) Plot a graph of race speeds versus practice speeds for each event.
c) Calculate the percentage difference between race and practice speeds.
d) Conduct statistical tests on the variability of race and practice speeds.

Answer 1

To determine if Terri Vogel drives faster in races than she does in practices, we can conduct statistical tests on the variability of race and practice speeds.

Step-by-step explanation:

To answer the question of whether Terri Vogel drives faster in races than she does in practices, we can conduct statistical tests on the variability of race and practice speeds. By comparing the standard deviation of her race times with the standard deviation of her practice times, we can determine if there is a significant difference in the variability of her speeds. If the standard deviation of her race times is significantly larger than the standard deviation of her practice times, it suggests that she drives faster in races than in practices.
