A density curve of auniform distributiontakes the constant value
k
 over the interval from 0 to 1.5 and is zero outside that range of values. This means that data described by this distribution take values that are uniformly spread between 0 and 1.5.
What is the total area under this density curve?
What is the value of
k? (Round your answer to three decimal places.)
What percent of the observations lie above 0.9? (Round your answer to a whole number.)
What percent of the observations lie below 0.3? (Round your answer to a whole number.)
What percent of the observations lie between 0.3 and 0.9? (Round your answer to a whole number.)
