    Answer:

    190

    Step-by-step explanation:

    Given : sample of size (n) = 500

    Number of samples = 200

    Confidence interval (CI) = 95% = 0.95

    Now we have to calculate the number of confidence intervals are expected to contain the true value of the population proportion.

    =  95% of 200

    = 0.95 × 200

    = 190

    Therefore, expected samples are 190.
