The normality of the data has been confirmed. Construct a 90% confidence interval for o in millions of dollars. (Round your answers to three decimal places.) Cleanup costs ($ millions) County Broward 0.85 Escambia 0.69 Franklin 0.50 Pinellas 1.14 Santa Rosa 0.50 Walton 1.34 millions of dollars Interpret a 90% confidence interval for a. O We are 5% confident that a, the population standard deviation, lies outside these two values. O We are 90% confident that o, the population standard deviation, lies between these two values. O We are 99% confident that o, the population standard deviation, lies between these two values. O We are 95% confident that s, the sample standard deviation of the six counties in the sample, lies between these two values. O We are 2.5% confident that s, the sample standard deviation of the six counties in the sample, lies outside these two values. anhln in the Annendiy of Tahles to answer this question.
