Question

Claim: A minority of adults would erase all of their personal information online if they could. A software firm survey of 483 randomly selected adults showed that 43% 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. Tyne an integer or a decimal Do not round)

Answer 1

Given the claim that the minority of adults would erase their personal information online if they could

$\begin{gathered} \sigma=s\tan dard\text{ deviation} \\ \mu=\operatorname{mean} \\ \text{therefore population=p} \end{gathered}$

the parameter to be used to represent this claim will be

$p$

The information shows that 43% of the adults would erase their information online

This means that based on the logic, the percentage of the minority adults should be =43% of the adult population

$\begin{gathered} \text{percentage of minority=43\%=}\frac{43}{100}=0.43 \\ \text{therefore we can say that} \\ p=0.43 \end{gathered}$

The word "WOULD" is a word under probability but one thing is for sure the minority adults that would erase their information online will not be more than 43%

Considering the value of selected adults by the firm which is = 483

The population of minority adults will be calculated as

$\begin{gathered} \frac{43}{100}\times483=207.69 \\ so\text{ we can therefore say that } \\ p=207.69 \end{gathered}$

p=0.43 (In terms of percentage)

p=207.69 (in terms of the population)
