The IQ scores for a random sample of subjects with medium lead levels in their blood and another random sample of subjects with high lead levels in their blood are given below. Use a 0.05 significance level to test the claim that subjects with medium lead levels have full IQ scores with a higher median that the median full IQ score for subjects with high lead levels. Does lead level appear to affect full IQ scores? Click the icon to view the data table. First define the null and alternative hypotheses. Ho: The two samples come from populations with equal medians. H₁: The medium lead level population has a higher median IQ than the high lead lev Identify the test statistic. Let the medium lead level be sample 1. z = 1.37 (Round to two decimal places as needed.) Calculate the P-value. P-value = 3.841 (Round to three decimal places as needed.)

Transcribed Image Text:The IQ scores for a random sample of subjects with medium lead levels
in their blood and another random sample of subjects with high lead
levels in their blood are given below. Use a 0.05 significance level to test
the claim that subjects with medium lead levels have full IQ scores with a
higher median that the median full IQ score for subjects with high lead
levels. Does lead level appear to affect full IQ scores?
Click the icon to view the data table.
First define the null and alternative hypotheses.
Ho: The two samples come from populations with equal medians.
H₁:
The medium lead level population has a higher median IQ than the high lead lev
Identify the test statistic. Let the medium lead level be sample 1.
z= 1.37
(Round to two decimal places as needed.)
Calculate the P-value.
P-value = 3.841
(Round to three decimal places as needed.)
