Question
You wish to test the following claim (Ha) at a significance level of a = 0.001.
H.:µ = 67.6
H:µ < 67.6
You believe the population is normally distributed and you know the standard deviation is o = 10.7. You
obtain a sample mean of æ= 63.1 for a sample of size n = 62.
What is the test statistic for this sample? (Report answer accurate to three decimal places.)
test statistic =
What is the p-value for this sample? (Report answer accurate to four decimal places.)
p-value
The p-value is...
O less than (or equal to) a
Ogreater than a
This test statistic leads to a decision to...
O reject the null hypothesis
accept the null hypothesis
fail to reject the null hypothesis
