Question

8. -2 points Let X denote the distance (m) that an animal moves from its birth site to the first territorial vacancy it encounters. Suppose that for banner-tailed kangaroo rats, has an exponential distribution with parameter = 0.01317 (a) What is the probability that the distance is at most 100 m? At most 200 m? Between 100 and 200 m? (Round your answers to four decimal places.) at most 100 m at most 200 m between 100 and 200 m (b) What is the probability that distance exceeds the mean distance by more than 2 standard deviations? (Round your answer to four decimal places.) (c) What is the value of the median distance? (Round your answer to two decimal places.) (d) Only 5% of animals will move farther than what distance? (Round your answer to two decimal places.) Show My Work (Optional) 9. -1 points Which statements are true about the standard normal distribution? The standard normal distribution is... (Select all that apply.) O symmetric. referred to as a bell-curve. U defined by the two parameters = 1, = 0 unimodal. U multimodal U defined by the two parameters = 0, =1 skewed. U a density curve Show My Work (Optional)
