Listed in the data table are IQ scores for a random sample of subjects with médium lead levels in their bi888. Also isted with high lead levels. Assume that the two samples are independent simple random samples selected from normally distributed populations. Do not assume that the population standard deviations are equal. Complete parts (a) and (b) below. Click the icon to view the data table of IQ scores. OA. Ho: #₁ =1₂ H₁: Hy #H₂ what are the null and alternative nypotneses?
