sssy In a sample of 134 ball bearings, the average diameter was found to be 3.78mm with a standard deviation of 0.44 . Give a point estimate for the population variance of the diameter of the ball bearings. Round your answer to two decimal places, if necessary.

Air Quality Index is a way to measure particle pollution in the air. An index between 0 and 50 is considered good; between 51 and 100 is moderate; more 100 is considered unhealthy for sensitive groups and others. A recent sample data of air quality index values for Pomona in Southern California provided the following data. 50, 52, 59, 56, 58 What are the sample mean, sample variance and the sample standard deviation?

High-power experimental engines are being developed by the Stevens Motor Company for use in its new sports coupe. The engineers have calculated the maximum horsepower for the engine to be 830HP . Twenty five engines are randomly selected for horsepower testing. The sample has an average maximum HP of 820 with a standard deviation of 80HP . Assume the population is normally distributed. Step 1 of 2 :  Calculate a confidence interval for the average maximum HP for the experimental engine. Use a significance level of α=0.1 . Round your answers to two decimal places.

The primary difference(s) between the standard deviation and the coefficient of variation as measures of risk are:

The average cost of tuition plus room and board for a small private liberal arts college is reported to be $8500 per term but I financial administrator boys that the average cost is half a study conducted using 350 small liberal arts colleges showed that the average cost per term is $8745 the population standard deviation is $1200 let a =0.05.what is the p-value for this test

A recent article in a business journal reported that the mean annual salary for graduates from 30 top MBA programs           10 years after graduation is  $275,000 Assume the standard deviation is $54,500 24 Keep the error probability at α = 0.05.  We want to build an interval which captures 95% of the sample means within ±$5,000 from the population mean.  What is the minimum sample size that would yield such an interval?                                     a 411                 b 457                 c 508                 d 564

The nutrition label for Oriental Spice Sauce states that one package of sauce has 1030 milligrams of sodium. To determine if the label is accurate, the FDA randomly selects 130 packages of Oriental Spice Sauce and determines the sodium content. The sample has an average of 1000.15 milligrams of sodium per package with a sample standard deviation of 271.69 milligrams. Step 1 of 2 : Calculate a 95% confidence interval for the mean sodium content in Oriental Spice Sauce. Round your answers to two decimal places.
