Question

Claim: Most adults would erase all of their personal information online if they could. A software firm survey of 693 randomly selected adults showed that 58% of them would oraso all of their personal information onlineif they could. Find the value of the test statistic

Answer 1

Total number of the adults are 693

Percentage of adults that show that they erase all of their personal information online is 58%

Geberal expression for the percentage is

`Percentage=\frac{\text{value to whose percentage to be found}}{\text{Total value}}*100`

We need to find the number of adults that erase all of their personal information online.

`Percantage=\frac{Number\text{ of the adults who erase thier personal informatio}}{\text{Total number of adults}}*100`

Substitute the value

Let x=Number of adults who erase thier personal information

`58=(x)/(693)*100`

Simplify and solve for, x

`\begin{gathered} 58*693=100x \\ (40194)/(100)=x \\ x=401.94 \end{gathered}`

Round of the x value

`x=402`

Number of adults who erase thier personal information are 402.
