Answer:
Alternative hypothesis Ha; is that the average time to accelerate from 0 to 60 miles per hour is greater than 7.7 seconds.
H0: u > 7.7
Step-by-step explanation:
The null hypothesis (H0) tries to show that no significant variation exists between variables or that a single variable is no different than its mean. While an alternative Hypothesis (Ha) attempt to prove that a new theory is true rather than the old one. That a variable is significantly different from the mean.
For the case above;
Let u represent the average time to accelerate from 0 to 60 miles per hour
Null hypothesis H0; is that the average time to accelerate from 0 to 60 miles per hour is equal to 7.7 seconds.
H0: u = 7.7
Alternative hypothesis Ha; is that the average time to accelerate from 0 to 60 miles per hour is greater than 7.7 seconds.
H0: u > 7.7
