Severity million pounds are grown in the US every year. Farm raised trout contain an average of 32 grams of fat per pound, with a standard deviation of 8grams of fat per pound. A random sample of 40 raised trout is selected. The mean fat content for the sample is 31.8 grams per pound, find the probability of observing a sample mean of 31.8 grams of fat per pound or less in a random sample of 40 farm raised trout
Please do not give solution in image format thanku A production process manufactures electronic components with timing signals whose duration follows a normal distribution. A random sample of 7 components was taken, and the durations of their timing signals were measured. a. The probability is 0.10 that the sample variance is bigger than what percentage of the population variance? b. The probability is 0.05 that the sample variance is less than what percentage of the population variance?
esc Introduction A chain of restaurants has historically had a mean wait time of 9 minutes for its customers. Recently, the restaurant added several very popular dishes back to their menu. Due to this, the manager suspects the wait time, μ, has increased. He takes a random sample of 44 customers. The mean wait time for the sample is 9.6 minutes. Assume the population standard deviation for the wait times is known to be 3.3 minutes. Can the manager conclude that the mean wait time is now greater than 9 minutes?

Determine whether you can use the normal distribution to approximate the binomial distribution. If you can, use the normal distribution to approximate the indicated probabilities and sketch their graphs. If you cannot, explain why and use the binomial distribution to find the indicated probabilities. A survey of adults in a region found that 33% name professional football as their favorite sport. You randomly select 11 adults in the region and ask them to name their favorite sport. Complete parts (a) through (d) below (a) Find the probability that the number who name professional football as their favorite sport is exactly 8.
PRACTICE ANOTHER Coal is carried from a mine in West Virginia to a power plant in New York in hopper cars on a long train. The automatic hopper car loader is set to put 82 tons of coal into each car. The actual weights of coal loaded into each car are normally distributed, with mean u = 82 tons and standard deviation o = 0.6 ton. (a) What is the probability that one car chosen at random will have less than 81.5 tons of coal? (Round your answer to four decimal places.) (b) What is the probability that 49 cars chosen at random will have a mean load weight x of less than 81.5 tons of coal? (Round your answer to four decimal places.) (c) Suppose the weight of coal in one car was less than 81.5 tons. Would that fact make you suspect that the loader had slipped out of adjustment? O Yes O No Suppose the weight of coal in 49 cars selected at random had an average x of less than 81.5 tons. Would that fact make you suspect that the loader had slipped out of adjustment? Why? O Yes, the…
