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 $0.09. What is the minimum number of gas stations that she should include in her sample if she uses the standard deviation estimate of $0.28, as reported in the popular press? (You may find it useful to reference the z table. Round intermedilate calculations to at least 4 decimal places and " value to 3 decimal places. Round up your answer to the nearest whole number.) Minimum number of gas stations

Estimation

A new framework of data analysis where the new statistical methods are used for interpreting the results and analyzing the data is known as estimation in statistics.

Question

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
$0.09. What is the minimum number of gas stations that she should include in her sample if she uses the standard deviation estimate
of $0.28, as reported in the popular press? (You may find it useful to reference the z table. Round intermediate calculations to at
least 4 decimal places and "" value to 3 decimal places. Round up your answer to the nearest whole number.)
