Questions have multiple answers!!

Question 1 A lab group investigates the maximum weight students can lift with their arms compared to their legs. If their t' value was 0.35, which of the following conclusions would be justified? They can't dertermine whether there is or is not a difference between the arms and legs data This is a difference between the arms and legs data. It's likely there's a difference between the arms and legs data. It's unlikely there's a difference between the arms and legs data. Question 2 For the preceding question, the correct answer is because .. the difference in means was abo at the same as the combined uncertainty. the difference in means was less than the combined uncertainty. the difference in means was greater than the combined uncertainty. there was a factor of 0.35 difference between the arms and legs data. Question 3 Another lab group measures the speed of cars on Aloma. They find: the 2-door cars had a mean speed of 49 mph with standard deviation of 5 mph . the 4-door cars had a mean speed of 45 mph with standard deviation of 6 mph If their t' = 15, what can you infer about their experiment? The speeds are too sim The means ./- standard deviations The different in means similar to the combat They probably measured a large number of cars
