    Answer:

    Original claim is explained below.

    Step-by-step explanation:

    p is the parameter who would erase all their personal i formation.

    p hat = 0.41 and it is the number of adults in the sample who would do that.This is the point of estimate.

    a. p=0.41, where p, the parameter, is the true proportion, as stated above.

    The null hypothesis p=0.41. We will never know what it is, but that is the hypothesis.

    The alternative hypothesis is p≠0.41.After that hypothesis we never know is it write or wrong. We can look at the sample and decide based on the p-value what the chances are that the parameter is truly 0.41 given the sample.We can create confidence interval which determine that true parameter lies in the interval.
