A researcher wants to determine if there is a significant difference in the standard deviations of the number of weekly physician office visits between residents in rural and urban areas of the country. A sample of 100 rural doctors report an average of 92.9 visits with a standard deviation of 18.4. A sample of 200 urban doctors reports an average of 92.4 times with a standard deviation of 19.5. Test at the .10 level of significance.
Use these instructions if they apply:
Show all calculations and circle the appropriate answers. Round only final calculations and do so to the correct decimal point. Use only the CLASSICAL APPROACH and show all SIX STEPS.
Show all formulas and circle the appropriate answers. Show all six steps, use the p-value approach using the TI-83 or TI-84 calculator (except if chi-square test or correlation).
