Question: Given below is the STATA output looking at the overall differences between three categories of lead exposure and the mean IQ for children. The exposure groups are defined as: 1 = control group, 2 = currently exposed & 3 = previously exposed.

Analysis of variance
source	ss	df	MS	F	Prob>F
Between groups	1600.097	2	800.048437	4.05	0.0199
Within groups	23919.1	121	197.678485
Total	25519.19	123	207.473118

Bartlett's test for equal variances : chi2(2) = 7.4930 Prob > chi2 = 0.024
Comparison of full scale iq by exposure group ( bonferroni)

Row mean- col Mean	1	2
2	-0.64189
2	1
3	8.64657	9.28846
3	0.024	0.064

[A] Justify the conclusion by describing the relevant information from the output.
[B] What do you conclude about the IQ of children and their exposure status?
