To determine the value of σp̂, we will use the formula:

\sigma_{\hat{p}} = \sqrt{\frac{p(1-p)}{n}}

Given x = 424 and n = 568, we can calculate p:

p = \frac{x}{n} = \frac{424}{568} \approx 0.746

Now we can plug in the values of p and n into the formula to calculate σp̂:

\sigma_{\hat{p}} = \sqrt{\frac{0.746(1-0.746)}{568}} \approx \sqrt{\frac{0.746 \times 0.254}{568}} \approx \sqrt{\frac{0.189484}{568}} \approx \sqrt{0.000333} \approx 0.018

Therefore, the value of σp̂ is approximately 0.018.

\boxed{0.018}

A popular cell phone family plan provides 1500 minutes. It charges 89.99/month for the first 2 lines and 9.99 for every line after that. Unlimited text messages for all phone lines costs $30.00/month, and Internet costs $10.00/month per phone line. If a family with a $200 monthly budget buys this plan and signs up for unlimited text messaging and Internet on each phone line, how many cell phone lines can they afford?
