Q.N. 3)The mean output of a certain type of amplifier is 344 watts with a variance of 100. If 74 amplifiers are sampled, what is the probability that the mean of the sample would differ from the population mean by less than 3 watts?
How do you find this answer on a TI-84 PLUS calculator? The mean output of a certain type of amplifier is 498 watts with a standard deviation of 12 watts. f 86 amplifiers are sampled, what is the probability that the mean of the sample would differ from the population mean by less than 1.1 watts? Round your answer to four decimal places.
Suppose the horses in a large stable have a mean weight of 807lbs, and a variance of 5776. What is the probability that the mean weight of the sample of horses would differ from the population mean by greater than 18lbs if 41 horses are sampled at random from the stable? Round your answer to four decimal places.
1) Suppose cattle in a large herd have a mean weight of 1169lbs and a variance of 17,161. What is the probability that the mean weight of the sample of cows would differ from the population mean by greater than 12lbs if 145 cows are sampled at random from the herd? Round your answer to four decimal places. 2) The mean lifetime of a tire is 36 months with a variance of 49. If 126 tires are sampled, what is...
An operation manager at an electronic company wants to test their amplifiers. The design engineer claims they have a mean output of 368 watts with a standard deviation of 12 watts. What is the probability that the mean amplifier output would differ from population mean by less than 3.8 watts in a sample of 84 amplifiers if the claim is true. Round answer to 4 decimal places
Suppose the horses in a large stable have a mean weight of 873lbs, and a variance of 17,161. What is the probability that the mean weight of the sample of horses would differ from the population mean by greater than 15lbs if 50 horses are sampled at random from the stable? Round your answer to four decimal places
The mean lifetime of a tire is 41 months with a variance of 64. If 100 tires are sampled, what is the probability that the mean of the sample would be greater than 41.88 months? Round your answer to four decimal places.
The variance of the scores on a skill evaluation test is 143,641 with a mean of 1517 points. If 343 tests are sampled, what is the probability that the mean of the sample would differ from the population mean by more than 36 points? Round your answer to four decimal places.
