According to the Department of Health, Statistics Students sleep an average of 8 hours a night. Assume that ‘hours of sleep a night’ follows a normal distribution with a standard deviation of 1.5 hours. If a statistics student is selected at random what is the probability they sleep less than 6 hours a night? If a statistics student is selected at random what is the probability they sleep more than 8.5 hours a night? If a statistics student is selected at random what is the probability they sleep between than 5 hours and 9 hours a night?
For a standardized psychology examination intended for psychology majors, the historical a data show that scores have a mean of 520 and a standard deviation of 170. The grading process of this year's exam has just begun. The average score of the 35 exams graded so far is 524. What is the probability that a sample of 35 exams will have a mean score of 524 or more if theexam scores follow the sane distribution as in the past? Carry computations to 4 decimal places, round your answer to 3.
The average number of shoppers at a particular grocery store in one day is 505, and the standard deviation is 115. The number of shoppers is normally distributed. For a random day, what is the probability that there are between 200 and 400 shoppers at the grocery store? The answer should be typed as a decimal with 4 decimal places.
Tom works for a fruit company and found that the weight of pineapples are normally distributed with mean is 500 grams and standard deviation is 100 grams. If he randomly chooses 16 pineapples and measure their weights, what is the probability that the average weight is more than 475 grams?
An elevator has a play card stating that the maximum capacity is 1980 pounds 12 passengers so 12 adult male passages can have a mean way of up to 1180÷12 = 165 pounds. If the elevator is loaded with 12 adult male passengers, find the probability that it is overloaded because they have a mean weight greater than 165 lb. Assume that weights of males are normally distributed with a mean of 172 pounds and a standard deviation of 27 pounds. Does this elevator appear to be safe?
Suppose that the amount of time that students spend studying in the library in one sitting is normally distributed with mean 48 minutes and standard deviation 23 minutes. A researcher observed 14 students who entered the library to study. Round all answers to 4 decimal places where possible. If one randomly selected student is timed, find the probability that this student's time will be between 42 and 50 minutes. For the 14 students, find the probability that their average time studying is between 42 and 50 minutes. Find the probability that the randomly selected 14 students will have a total study time less than 714 minutes.
The life of light bulbs is distributed normaly, The variance of the lifetime is 900 and the mean lifetime of a bulb is 550 hours. Find the probablty of abulb lasting forat least 583 hours. Round your anvwer to four decimal places
Suppose the length of the pregnancies of a certain animal are approximately normally distributed with mean =300 days and a standard deviation =26 days. The probability that the mean of a random sample of 15 pregnancies is less than 291 days is approximately what? (Round to 4 decimal points)
Procter and Gamble reported that an American family of four washes an average of 2000 pounds of clothes each year. If the standered deviation of the distribution is 187.5 pounds, find the probability that the mean of a randomly selected same of 50 families of 4 will be less that 1950 pounds. Round your awnser to four decimal places and assume the variable is normally distributed
