The noon winter temperature in Chicago is normally distributed with a mean of 36 degrees Fahrenheit and standard deviation of 4. Which of the following statements is correct? It is more likely that the temperature observed will be colder than 36 degrees than warmer. Fifty percent of the temperatures observed are warmer than 36 degrees. A temperature observation of 36±0.5 degrees is more likely than one of 35±0.5 degrees. The variance of the noon winter temperature in Chicago is 16 degrees squared. There is more than 99% chance that the temperature oscillates between 24 and 48 degrees Fahrenheit.
