Assume that a sample is used to estimate a populationmean u. Find the 80% confidence interval for a sample ofμ.size 40 with a mean of 68.2 and a standard deviation of12.1. Enter your answer as an open-interval (i.e.,parentheses) accurate to one decimal place (because thesample statistics are reported accurate to one decimalplace).80% C.I. =Answer should be obtained without any preliminaryrounding. However, the critical value may be rounded to 3decimal places.

Confidence interval can be calculated using this formula: CI = x̄ + t nswhere:x̄ = sample mean =…

An IQ test is designed so that the mean is 100 and the standard deviation is 10 for the population of normal adults. Find the sample size necessary to estimate the mean IQ score of statistics students such that it can be said with 90% confidence that the sample mean is within 2 IQ points of the true mean. Assume that o = 10 and determine the required sample size using technology. Then determine if this is a reasonable sample size for a real world calculation. The required sample size is (Round up to the nearest integer.) Enter your answer in the answer box and then click Check Answer. ? 1 part remaining Check Answer 1 Clear All

Assume all populations are normally distributed. A travel analyst claims that the mean price of a round trip flight from New York City to Los Angeles is less than $507. In a random sample of 55 round trip flights from NYC to LA, the mean price is $502. Assume the population standard deviation is $111. At α = 0.05, is there enough evidence to support the travel analyst’s claim?
