Find a 99% confidence interval for ?1 − ?2. (Round your answers to two decimal places.) lower limit: upper limit: Which distribution did you use? Why? A) The standard normal distribution was used because ?1 and ?2 are unknown. B) The Student's t-distribution was used because ?1 and ?2 are known. C) The Student's t-distribution was used because ?1 and ?2 are unknown. D) The standard normal distribution was used because ?1 and ?2 are known. Do you need information about the petal length…
