Choose all the right choices from below (There could be more than one choice that is right.And there could be choices that are incorrect.Choosing wrong choices will attract negative marking) For a normal distribution with mean 350 and standard deviation 30, the random value of x=320

a.Is exactly one standard deviation to the left of the mean

b.Has a z score of +1

c.Is more than Q1 (first quartile)

d.Has a zero probability of happening since x follows a continuous distribution

e.Hasa z score -1

f.Is less than Q1

g.Has a very low but still significant chance of happening

h.Is exactly one standard deviation to the right of the mean

Identify the true statement

a.To compute the probability of a random number being higher than a particular value, you can commulative particular value and subtract it from 1

b.To compute the probability of a random number being in between two specificvalues, we can cumulative number and subtract this from the cumulative probability for the smaller number

c.Excel cannot be used to compute the probability of a random number being higher than a particular

d.Excel cannot be used to compute the probability of a random number being in between two
