    B

    Step-by-step explanation:

    To construct a confidence interval estimate, the sample must be randomized. Hence option A is a requirement.

    The data must follow normal distribution pattern or at least nearly normal distribution condition. Hence, option D is also a must for confidence interval estimate.

    Normal distribution can be shown with a data with histogram graph with a bell-shaped showing a balanced proportion of data, hence option C is also true.

    While option B with population skewed to the right shows negative distribution which will have mean to the right of the median. Hence B is not the requirement for confidence interval estimate for a population variance.
