A sample of 62 city blocks were taken in Black majority neighborhoods and 58 city blocks in non-Black majority neighborhoods. We are interested in looking at the concentration of Nitrogen Dioxide (NO2), an air pollutant. The average amount of NO2 in Black majority blocks is 11.0362 with a standard deviation of 4.3976, and the average amount of NO2 in non-Black majority blocks is 10.4195 with a standard deviation of 4.9371. Test the claim that the mean NO2 concentration is greater in Black majority than non-Black majority blocks at a = 0.10. Assume that the data come from normal populations with equal variances. Round your answers to three decimal places, and round any interim calculations to four decimal places.
