Answer:

Option B

Step-by-step explanation:

Here ,

The mean value is 0.62

Z value formula is

z = (x' -mean)/(sigma/sqrt (n))

Substituting the given values, we get -

sigma = Sqrt {(x'-mean)^2/n}

Sigma = sqrt { (0.58-0.62)^2/75} = 0.09

z = (0.58-0.62)/(0.09)

z = -0.433

Hence, option B is correct
