Various temperature measurements are recorded at different times for a particular city. The mean of 20 o C is obtained from a sample of 32 temperatures. If we know that historically for this city the mean daily temperature is μ = 22 o C and that σ = 3.5 o C , test the claim that the city is actually colder than now than previously believed. Use α = .01 for this problem. Round all values to three decimal places...

If you lose, the net benefit is minus $10 (the cost of the ticket). 2. Your car insurance company has learned, from years...
