probability that between 10.5 gallons and 11.5 gallons are pumped during

a randomly selected minute3. describe a uniform distribution 4. the area under a standard normal density curve with mean of 0 and standard deviation of 1 in________?5. what three values are equal in a normal distribution?6. Suppose that prices of a certain model of new homes are normally

distruted with a mean of $142000 and a standard deviation of $1100 find
