= for x in [4,9]. 1 The length (in centimeters) of a petal on a certain flower is a random variable with probability density function defined by f(x) = 2vx a. Find the expected petal length. b. Find the standard deviation. c. Find the probability that a petal selected at random has a length less than 2 standard deviations below the mean. d. Find the median petal length. a. The expected petal length is 6.333 cm. (Round to three decimal places as needed.) b. The standard deviation is o = cm. (Round to three decimal places as needed.) c. The probability that a petal selected at random has a length less than 2 standard deviations below the mean is (Round to three decimal places as needed.) d. The median petal length is cm. (Round to three decimal places as needed.)
