Question

​Claim: Most adults would erase all of their personal information online if they could. A software firm survey of 417 randomly selected adults showed that 55​% 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

We claim most of the adults which indicates more than 50% or .50...let population proportion be p ..so p>.50..The null hypothesis states that the population proportion is equal to the value mentioned in the claim...so Ho:p=0.50..

The claim is either the null hypothesis or the alternative hypothesis...if the null hypothesis is the claim...then the alternative hypothesis states the opposite of null hypothesis...Ha:p>.50

Hence

Ho:p=.50

at Ha:p>.50
