Question

claim: Most adults would not erase all of their personal information online if they could. A software firm survey of 544 randomly selected adults showed that 41​% of them would erase all of their personal information online if they could. Complete parts​ (a) and​ (b) below. a. Express the original claim in symbolic form. Let the parameter represent the adults that would erase their personal information.

Answer 1

Original claim is explained below.

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.
