3. Use the following measured amounts of carbon monoxide in Los Angeles and San Francisco. Notethat corresponding entries are from the same day, so they data are matched by the days theyrepresent. For the population differences, use a 0.05 significance level to test the claim that thedifferences have a mean equal to 0.Carbon Monoxide in Los Angeles (ppm)1.41 1.23 1.21 1.02 0.86 1.17 1.31 1.29 1.37 1.13 0.67 0.88 0.92 1.14 1.10 1.191.53 1.30 1.54 1.30 0.89 1.16 0.96 | 1.60 1.30 0.84 0.67 0.82 0.80 0.74 0.84 0.92Carbon Monoxide in San Francisco (ppm)0.530.56 | 0.71 0.60 0.65 0.72 0.95 0.94 0.63 0.41 0.46 0.54 0.66 0.60 0.63 0.700.54 0.51 0.60 0.65 0.51 0.78 0.66 0.57 0.72 0.73 0.77 0.72 0.59 0.61 0.660.484. A flight is considered to be on time if it arrives no later than 15 minutes after the scheduled arrivaltime. For a recent year, American Airlines flew flights from New York (JFK) to Los Angles InternationalAirport. Among 24 Sunday flights, 14 arrived on in Los Angles on time. Among 65 Friday flights, 50arrived on time. The data are from the Department of Transportation. Use a 0.05 significance level totest the claim that on-time rates are the same for Sundays and Fridays.
