Question

Claim: A majority of adults would erase all of their personal information online if they could. A software firm survey of 498 randomly selected adults showed that 62% 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.
(Type an integer or a decimal. Do not round.)

Answer 1

Let p be the proportion of all adults who would erase all of their personal information online if they could. Then the original claim can be expressed in symbolic form as:

p > 0.5

In words, the claim is that the proportion of adults who would erase all of their personal information online if they could is greater than 0.5 (which represents a majority).
