Julie was testing how far two new electric cars-model A and model B-could drive on a full charge. She obtained a sample of 5 new cars of each model, charged them fully, and drove them as far as she could along a controlled route. Here is a summary of the distances: Distance Model A Model B Mean 168 km 172 km Standard deviation 5.4 km 7.5 km Number of cars 5 5 Julie wants to use these results to test Ho: HA - HB = 0 versus Hạ: Ha – HB # 0. Assume that these are representative samples and all other conditions have been met. What is the P-value associated with these sample results? 0.10 < P-value < 0.20 0.05 < P-value < 0.10 P-value < 0.01 0.01< P-value < 0.05 P-value > 0.20

Transcribed Image Text:Julie was testing how far two new electric cars-model A and model B-could drive on a full charge. She
obtained a sample of 5 new cars of each model, charged them fully, and drove them as far as she could
along a controlled route. Here is a summary of the distances:
Distance
Model A Model B
Mean
168 km 172 km
Standard deviation 5.4 km 7.5 km
Number of cars

5
Julie wants to use these results to test Ho: Ha – HB = 0 versus Ha: µA – HB + 0. Assume that these
are representative samples and all other conditions have been met.
What is the P-value associated with these sample results?
0.10 < P-value < 0.20
0.05 < P-value < 0.10
P-value < 0.01
0.01< P-value < 0.05
O P-value > 0.20
