You wish to test the following claim (Ha) at a significancelevel of ?=0.001.
Ho:?=57.4
Ha:?>57.4
You believe the population is normally distributed and you know thestandard deviation is ?=6.6. You obtain a sample mean of M=59.7 fora sample of size n=72.
What is the critical value for this test? (Report answer accurateto three decimal places.)
critical value =
What is the test statistic for this sample? (Report answer accurateto three decimal places.)
test statistic =
The test statistic is...
in the critical region
not in the critical region
This test statistic leads to a decision to...
reject the null
accept the null
fail to reject the null
As such, the final conclusion is that...
There is sufficient evidence to warrant rejection of the claimthat the population mean is greater than 57.4.
There is not sufficient evidence to warrant rejection of theclaim that the population mean is greater than 57.4.
The sample data support the claim that the population mean isgreater than 57.4.
There is not sufficient sample evidence to support the claimthat the population mean is greater than 57.4.
