Question
You wish to test the following claim (Ha) at a significance level of a = 0.05.
Н.: д — 78.1
На: и > 78.1
You believe the population is normally distributed, but you do not know the standard deviation. You obtain
the following sample of data:
data
133
62.1
105.7
97.7
117.8
What is the test statistic for this sample? (Report answer accurate to 3 decimal places.)
test statistic =
What is the P.value for this sample? (Report answer accurate to 3 decimal places.)
P-value =
The P-value is...
O less than (or equal to) a
O greater than a
This test statistic leads to a decision to...
O reject the null
O fail to reject the null
As such, the final conclusion is that...
O The sample data support the claim that the population mean is greater than 78.1.
O There is not sufficient sample evidence to support the claim that the population mean is greater
than 78.1.
