Find the probability that a single randomly selected value is greater than 301. Round your answer to four decimals. P (X> 301)= b. WebDec 11, 2013 · You cannot tell from only 2 samples whether they are normally distributed or not. If you have a larger sample set and you are only testing them in pairs, then you could use the larger sample set to test for a particular distribution.
