"Trydint" bubble-gum company claims that 7 out of 10 people prefer their gum to "Eklypse". Test their claim at the 99 confidence level.
The null and alternative hypothesis in symbols would be:
![Based on a sample of 240 people, 162 said they prefer "Trydint" gum to "Eklypse".
The point estimate is: 0.675
(to 3 decimals)
The 99 % confidence interval is: 0.629
decimals)
X to 0.721
x (to 3](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fd57b7bd0-b370-4b8a-8394-d17f179298c2%2F1e9e2f96-3d23-48ea-bedc-8207f187d515%2F9dy39yj_processed.png&w=3840&q=75)
