The conditional relative frequency table was generated by row using frequency table data comparing the hat size and shirt size o

f children on a baseball team. A 4-column table with 3 rows. The first column has no label with entries medium shirt, large shirt, total. The second column is labeled child-sized hat with entries almost equals 0.67, 0.2, 0.48. The third column is labeled adult-sized hat with entries almost equals 0.33, 0.8, 0.52. The fourth column is labeled total with entries 1.0, 1.0, 1.0. The coach attempts to determine an association between shirt size and hat size. Which is most likely true? An association cannot be determined because 0.48 is similar to 0.52. An association cannot be determined because the sum of each column is not 1.0. There is likely an association because 0.8 is not similar to 0.2. There is likely an association because 0.8 is not similar to 0.33.

Anon25 [30]

Answer:

A. E(x) = 1/n×n(n+1)/2

B. E(x²) = 1/n

Step-by-step explanation:

The n candidates for a job have been ranked 1,2,3....n. Let x be the rank of a randomly selected candidate. Therefore, the PMF of X is given as

P(x) = {1/n, x = 1,2...n}

Therefore,

Expectation of X

E(x) = summation {xP(×)}

= summation {X×1/n}

= 1/n summation{x}

= 1/n×n(n+1)/2

= n+1/2

Thus, E(x) = 1/n×n(n+1)/2

Value of E(x²)

E(x²) = summation {x²P(×)}

= summation{x²×1/n}

= 1/n
