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.
R-organisms are usually bellow carrying capacity (<span>the maximum size of some population that can survive in the given environment)</span>. Those organisms are small and produce a great number of offspring. However, their life expectancy is short and many individuals die within a short time. Because of the high rate of death, they do not live long enough to reach their carrying capacity. Their life span is short, so even if predators were removed from the population, it would not be expected they will reach their carrying capacity.
