A shareholders' group is lodging a protest against your company. The shareholders group claimed that the
You want to formulate and test a hypothesis that can be used to challenge the validity of the claim made by the group, at a significance level of α=0.02. Your hypotheses are:
Ho: μ≥ 8
Ha: μ< 8
What is the test statistic for this sample?
test statistic =
(Report answer accurate to 3 decimal places.)
What is the p-value for this sample?
p-value =
(Report answer accurate to 4 decimal places.)
The p-value is...
less than (or equal to) α
or
greater than α
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 claim that the population mean is less than 8.
There is not sufficient evidence to warrant rejection of the claim that the population mean is less than 8.
The sample data support the claim that the population mean is less than 8.
There is not sufficient sample evidence to support the claim that the population mean is less than 8.
