You can put this solution on YOUR website! If the claim says that the population mean is greater than 200 and the sample mean is 215, we can say that the claim is true even without a formal test
what is wrong with this statement
-----
Ho: u <= 200
Ha: u > 200 (claim)
----
The test results support the claim only if we reject Ho.
---
We reject Ho at the 95% significance level only if 215 is more than 1.96 standard deviations above the mean.
