A ski gondola carries skiers to the top of a mountain. Assume that weights of skiers are normally distributed with a mean of 182 lb and a standard deviation of 35 lb. The gondola has a stated capacity of 25 passengers and is rated for a load limit of 3500 lb. Complete parts (a) through (d) below.

a. Given that the gondola is rated for a load limit of 3500 lb, what is the maximum mean weight of the passengers if the gondola is filled to the stated capacity of 25 passengers?
- The maximum mean weight is 140 lb. (Type an integer or a decimal. Do not round.)

b. If the gondola is filled with 25 randomly selected skiers, what is the probability that their mean weight exceeds the value from part (a)?
- The probability is ______. (Round to four decimal places as needed.)

[Please complete the rest of the problem based on the given information.]

Answer :

Final answer:

The maximum mean weight of the passengers when the gondola is filled to capacity is 140 lb. To calculate the probability that the mean weight of 25 randomly selected skiers exceeds this value, we can use the Central Limit Theorem and z-scores.

Explanation:

To find the maximum mean weight of the passengers if the gondola is filled to the stated capacity of 25 passengers, we divide the load limit (3500 lb) by the number of passengers (25). Therefore, the maximum mean weight is 140 lb.

To calculate the probability that the mean weight of 25 randomly selected skiers exceeds 140 lb, we can use the Central Limit Theorem. We calculate the z-score for 140 lb using the formula: z = (x - μ) / (σ / sqrt(n)). Once we have the z-score, we can use a standard normal distribution table or calculator to find the probability that the z-score is greater than the calculated value.

Therefore, the probability that the mean weight exceeds the value from part (a) is the probability of the z-score being greater than the calculated value.
