**Transcription for Educational Website****Sample Analysis of Aluminum-Alloy Channels**Samples of aluminum-alloy channels were tested for stiffness. The following frequency distribution was obtained. The distribution is assumed to be normal.| **Stiffness** | **Frequency** ||---------------|---------------|| 2480 | 23 || 2440 | 35 || 2400 | 40 || 2360 | 33 || 2320 | 21 |**Question:**What is the approximate mean of the population from which the samples were taken?- [ ] 2367- [ ] 2398- [ ] 2402- [ ] 2419**Explanation:**This table presents a frequency distribution of stiffness values observed in aluminum-alloy channels. Each stiffness value corresponds to the number of samples exhibiting that specific stiffness. The goal is to determine the mean stiffness of the sampled population, which can be approximated using statistical methods.

A boat capsized and sank in a lake. Based on an assumption of a mean weight of 133 Ib, the boat was rated to carry 70 passengers (so the load limit was 9,310 Ib). After the boat sank, the assumed mean weight for similar boats was changed from 133 lb to 174 lb. Complete parts a and b below. a. Assume that a similar boat is loaded with 70 passengers, and assume that the weights of people are normally distributed with mean of 181.1 Ib and a standard deviation of 38.6 lb. Find the probability that the boat is overloaded because the 70 passengers have mean weight greater than 133 lb The probability isO: (Round to four decimal places as needed.) b. The boat was later rated to carry only 17 passengers, and the load limit was changed to 2,958 Ib. Find the probability that the boat is overloaded because the mean weight of the passengers is greater than 174 (so that their total weight is greater than the maximum capacity of 2,958 Ib). The probability is. (Round to four decimal places as needed.)…
