Answer:
The answer is B) arachnoid granulations
Explanation:
Arachnoid Mater and CSF Circulation:
- The arachnoid is the middle layer of the meninges which are the membranes covering the brain.
- The arachnoid is characterized by the spider web like projections that extend between it and the pia mater (outer membrane of the meninges).
- These projections are located in the subarachnoid space (space below the arachnoid). These projections contain the circulating cerebrospinal fluid or CSF.
- The arachnoid extends into the dural sinuses through the arachnoid granulations in which the CSF is filtered and added to the blood for drainage from the brain.

Answer:
The correct answer is paired sample t-test.
Explanation:
Based on the given information, the mothers living in poverty in the United States give birth to underweight babies. The average weight of the babies given birth by women living in poverty is 2.8 kg. To examine the efficacy of a novel prenatal care program, a test was conducted by the CDC in which 30 mothers living in poverty and the weights of their babies were recorded.
As the test is conducted in pairs, thus, paired sample t-test would be the appropriate hypothesis test. The paired t-test is performed when the dependent variable is measure spontaneously. In the given case, the women participating in the program and the number of babies with less birth weight are examined in pairs. Thus, as the sample are paired together, the correct answer would be paired sample t-test.
