Question

**Claim:** A majority of adults would erase all of their personal information online if they could. A software firm survey of 424 randomly selected adults showed that 60% 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.

**\[p\] \gt 0.50**
(Type an integer or a decimal. Do not round.)

**b.** Identify the null and alternative hypotheses.

\[ H_0: p \leq 0.50 \]
\[ H_1: p \gt 0.50 \]
(Type integers or decimals. Do not round.)

In the symbolic form and hypotheses provided, $ p $ represents the population proportion of adults who would erase all of their personal information online if they could. The null hypothesis ( $ H_0 $ ) suggests that 50% or fewer adults would erase their personal information, while the alternative hypothesis ( $ H_1 $ ) suggests that more than 50% would do so.
