Question 581324
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.
