Answer:
a. 0.15%
Step-by-step explanation:
The Z-score of a 945-lb car is ...
(X -μ)/σ = (945 -3550)/807 ≈ -3.23
The empirical rule tells you that about 99.7% of the normal distribution is within 3σ of the mean, so less than 1/2 of 0.3% will be more than 3σ below the mean. The most appropriate of these choices is 0.15%.
_____
The CDF of a normal distribution changes rapidly in the tails, so the difference between 3σ and 3.23σ is pretty large. The actual probability is nearer 0.062%.
