    Step-by-step explanation:

    In Statistitics whenever we test a hypothesis for testing a statistic, we use confidence interval.

    Confidence interval is on either side of an assumed value a margin of error

    Margin of error is calculated as critical value * sigma/sqrt of n

    Thus we find that whenever n increases, margin of error decreases, thus making confidence interval narrower and thus making probability for accepting null hypothesis a less value.

    Thus we find that option C is right.

    C. Increasing the sample size decreases the probability because σx decreases as n increases.
