To test the claim that a population has a mean less than 100, the test statistic was z= -1.8. What was the p-value?
Homework Answers
Answer #1
p-value
Since the alternative is less than, we are to calculate:
, where 
Since the p-value is less than 0.05, we reject the Null Hypothesis
and claim that the mean is less than 100.

You wish to test the
claim that the average IQ score is less than 100 at the .005
significance level. You determine the hypotheses are:
Ho: μ=100
H1:μ<100
You take a simple
random sample of 76 individuals and find the mean IQ score is 95.5,
with a standard deviation of 15.1. Let's consider testing this
hypothesis two ways: once with assuming the population standard
deviation is not known and once with assuming that it is known.
