Suppose that the contagious period of COVID-20 has an average of 7 days, and follows a chi-square distribution.  Let X measure the contagious period for a randomly selected specimen of the COVID-20 virus. State the distribution of the random variable X. Group of answer choices X∼χ2(6) X∼Student′st(7) X∼χ2(7) X∼Continuous(7)     A friend of yours has COVID-20 and the doctors have told her that she has had it for 10 days.  Compute the probability that they are still contagious.  (I.E. compute the probability that X is greater than or equal to 10 days.)
