Because of bad weather, the number of days next week that the captain of a charter fishing boat can leave port is uncertain. Let x = number of days that the boat is able to leave port per week. The probability distribution shown to the right for the variable, x, was determined based on historical data when the weather was poor. Based on the probability distribution, what is the expected number of days per week the captain can leave port? Find the expected number of days per week the captain can leave port. (Type an integer or a decimal.) X 0 1 2 3 4 5 6 7 P(x) 0.05 0.10 0.15 0.20 0.25 0.10 0.10 0.05
Suppose a random variable, x, has a uniform distribution with a = 5 and b = 13. a. Calculate P(7.5 ≤x≤ 10). b. Determine P(x < 9). c. Compute the mean, μ, and the standard deviation, o, of this random variable. d. Determine the probability that x is in the interval (μ ± 20).
A continuous random variable is uniformly distributed between 200 and 220. a. What is the probability a randomly selected value will be greater than 215? b. What is the probability a randomly selected value will be less than 205? c. What is the probability a randomly selected value will be between 205 and 215?
