Coal is carried from a mine in West Virginia to a power plant in New York in hopper cars on a long train. The automatichopper car loader is set to put 71 tons of coal into each car. The actual weights of coal loaded into each car are normallydistributed, with mean u = 71 tons and standard deviation = 0.7 ton.USE SALT(a) What is the probability that one car chosen at random will have less than 70.5 tons of coal? (Round youranswer to four decimal places.)2375(b) What is the probability that 29 cars chosen at random will have a mean load weight x of less than 70.5 tons ofcoal? (Round your answer to four decimal places.)(c) Suppose the weight of coal in one car was less than 70.5 tons. Would that fact make you suspect that theloader had slipped out of adjustment?YesNotSuppose the weight of coal in 29 cars selected at random had an average x of less than 70.5 tons. Would that factmake you suspect that the loader had slipped out of adjustment? Why?Yes, the probability that this deviation is random is very small.Yes, the probability that this deviation is random is very large.No, the probability that this deviation is random is very small.No, the probability that this deviation is random is very large.

Q. 1 t is estimated that 809% of emails are spam emails. Some software has been applied to filter these spam emails before they reach our inbox. A certain brand of software claims that it can detect 99% of spam emails, and the probability for a false positive (a non-spam email detected as spam) is 5%. Now if an email is detected as spam, then what is the probability that it is in fact a non-spam email? event A: email is spam; event B: email is detected as spam. Assume that

The probability of afternoon rain given morning cloud cover >50% is of interest to those forecasting the weather. You can calculate this probability using Bayes' Theorem (below). The probability of morning cloud cover in general is 30% in the area you are concerned with and when there's afternoon rain, morning cloud cover of the kind described above occurs 90% of the time. The probability of rain in general for the area is about 26% of days. From the above information, identify what P(BIA) would be. Express your answer as a proportion, rounded to two decimal places. P(A/B)= = P(B|A)*P(A) P(B)
