Beer bottles are filled so that they contain an average of 450 ml of beer in each bottle. Suppose that the amount of beer in a bottle is normally distributed with a standard deviation of 7 ml. a. What is the probability that a randomly selected bottle will have less than 444 ml of beer? (Round answer to 4 decimal places.)

The standard deviation of the scores: 2, 1, 1, 8 is O 1.71 2 2.92 O.8.5

According to a study done by De Anza students, the height for Asian adult males is normally distributed with an average of 66 inches and a standard deviation of 2.5 inches. Suppose one Asian adult male is randomly chosen. Let X = height of the individual. Find the probability that the person is between 64 and 69 inches. The middle 40% of heights fall between what two values?Write the probability statement. State the two values. (Round your answers to one decimal place.) x1,x2   ch6#9

The average yearly salary for an electrician is $51853. Suppose that the distribution is normal with a standard deviation equal to $4850. What is the probability that a random sample of 35 electricians had a mean income greater than $50123? Less than $49730? Assume that the sample is taken from a large population and the correction factor can be ignored. Express each probability as a percent rounded to two decimal places. Income greater than $50123: ____%Income less than $49730: _____%
