Why is it important to check the 10% condition before calculating probabilities involving x –? select one:

a) to reduce the variability of the sampling distribution of x –.
b) to ensure that the distribution of x – is approximately normal.
c) to ensure that we can generalize the results to a larger population.
d) to ensure that x – will be an unbiased estimator of m.
e) to ensure that the observations in the sample are close to independent.
