K Listed in the data table are IQ scores for a random sample of subjects with medium lead levels in their blood. Also listed are statistics from a study done of IQ scores for a random sample of subjects 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. Hot=12 H₁ 11 #1₂ Ho H1 =12 H₁ H₁ H₂ The test statistic is Ho: Hy #H2 Hy: Hy > H2 Ho. Hi F12 H₁: Hy > H₂ (Round to two decimal places as needed)

Listed in the data table are IQ scores for a random sample of subjects with medium lead levels in their
blood. Also listed are statistics from a study done of IQ scores for a random sample of subjects 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.

Ho H₁-H2
H₁ 11 #1₂
Ho H1 =12
H₁ H1 H₂
The test statistic is
Ho. Hy #H2
Hy: Hy > H2
Ho H = 12
H₁: Hy > H₂
