Maddie is a vlogger who creates makeup tutorial videos. The site that hosts her videos recently demonitized her channel because her ad click-through rate fell below 4.7%. To test this claim, she randomly selected 800 subscribers and found that 30 of them had clicked on the last ad that they saw.

Use Excel to test whether the website's claim is true that less than 4.7% of the ads shown during her videos are clicked on, and then draw a conclusion in the context of the problem. Use=0.05.
