An exothermic reaction is performed in a bioreactor, attached with a controller which is used to
maintain the temperature in the bioreactor between certain limits. During a long time period, the
temperature in the bioreactor is measured, and mean and variance of the variable are observed as 22o
and 8o, respectively. Assuming that temperature is normally distributed in the bioreactor, calculate the
probability of observing a temperature between 24o and 28o at some instant?
