An economist would like to estimate the 95% confidence interval for the average real estate taxes collected by a small town in California. In a prior analysis, the standard deviation of real estate taxes was reported as $1,590. [You may find it useful to reference the z table.] What is the minimum sample size required by the economist if he wants to restrict the margin of error to $430? (Round intermediate calculations to at least 4 decimal places and "z" value to 3 decimal places. Round up your answer to the nearest whole number.)

An economist would like to estimate the 99% confidence interval for the average real estate taxes collected by a small town in California. In a prior analysis, the standard deviation of real estate taxes was reported as $1,520.

a. An analyst from an energy research institute in California wishes to estimate the 95% confidence interval for the average price of unleaded gasoline in the state. In particular, she does not want the sample mean to deviate from the population mean by more than $0.06. What is the minimum number of gas stations that she should include in her sample if she uses the standard deviation estimate of $0.35, as reported in the popular press? Round intermediate calculations to...

An analyst from an energy research institute in California wishes to estimate the 99% confidence interval for the average price of unleaded gasoline in the state. In particular, she does not want the sample mean to deviate from the population mean by more than $0.13.

In a sample of 430 residents of Georgetown County, 165 reported they believed the county real estate taxes were too high. Develop a 95 percent confidence interval for the proportion of residents who believe the tax rate is too high. (Round the p(proportion) value to 2 decimal places and final answers to 3 decimal places.) Confidence interval for the proportion of residents is up to . Would it be reasonable to conclude that the majority of the taxpayers feel that the taxes...

Suppose you are told that a 95% confidence interval for the average price of a gallon of regular gasoline in your state is from $3.04 to $3.61. Use the fact that the confidence interval for the mean is in the form x − E to x + E to compute the sample mean and the maximal margin of error E. (Round your answers to two decimal places.)
