A survey of 100 businesses revealed that the mean after-tax profit was $80,000. Assume the population standard deviation is $15,000. Using a 95% confidence level, calculate the confidence interval of the mean after tax profit. Lower Class Limit = Round the final answer to the nearest dollar. Upper Class Limit = Round the final answer to the nearest dollar.

Hypothesis test of proportions On April 15th 1912, the R.M.S. Titanic sank into the north atlantic ocean resulting in th loss of more than 1500 passengers and crew. Below is a number of passengers and crew of survivors for the crew, first, second, and third class. Find the proportion of survivors by type of service crew, first, second and third. Test the hypothesis at the 99% confidence level that the proportion of first class survivors is the same as third class (25) What do you calculate for the test statistic: c? what is the critical sttistic? What is the conclusion of your hypothesis test? class passengers survived crew 885 212 first 325 202 second 285…

Hypothesis test For a certain nationwide standardized test there are two commonly used preparation products on the market: StudyFocus and Prepara. A researcher in the Education department at a nearby university wants to determine if there is any difference between the two products on the mean score on the test by their users. The researcher obtains the scores on the test from a random sample of 16 users of StudyFocus and a random sample of 14 users of Prepara. (These samples are chosen independently.) These data are shown in the table. ? StudyFocus Prepara Send data to calculator 408, 400, 460, 587, 485, 559, 470, 439, 453, 531, 491, 481, 529, 494, 581, 397 510, 553, 504, 525, 549, 500, 525, 561, 510, 493, 498, 512, 517, 546 V Scores Send data to Excel Perform a two-tailed test.

STATISTICAL ANALYSIS (No long explanation needed. Rate will be given and write the complete solutions.) CI on Mean, Variance Unknown, Prediction and Tolerance Interval A CNC (computer numerical control) machine produces iron automobile crankshafts. Samples are measured and the inner diameter are found to be 1.01, 0.97, 1.03, 1.04, 0.99, 0.98, 0.99, 1.01, and 1.03 centimeters. For all computations, assume an approximately normal distribution. The sample mean and standard deviation for the given data are = 1.0056, and s = 0.0246. Find a 99% confidence interval on the mean of diameter. Compute a 99% prediction interval on a measured diameter of a single crankshaft piece taken from the machine. Find the 99% tolerance limits that will contain most of the metal pieces produced by the CNC machine. Choose the correct answer. a. CI on the mean: 0.970 < μ < 1.9845.
