HERLet x be the number of courses for which a randomly selected student at a certain university is registered. The probabilitydistribution of x appears in the following table.146.P(x)0.030.040.090.240.400.140.06It can be easily verified that u = 4.6 and o = 1.29.(a) Because u – o = 3.31, the x values 1, 2, and 3 are more than 1 standard deviation below the mean. What is theprobability that x is more than 1 standard deviation below its mean?(b) What x values are more than 2 standard deviations away from the mean value (either less than u – 20 or greaterthan u + 20)? (Select all that apply.)Ox = 1Ox = 2Ox = 3Ox = 4Ox = 5O x = 6Ox = 7(c) What is the probability that x is more than 2 standard deviations away from its mean value?
