Well it's thought that the oxygenation of the atmosphere contributed to the evolution
Answer:
Carbon dioxide
Explanation:
The Lewis structure of carbon dioxide shows that the carbon in CO2 must make 2 sigma bonds and it has no lone pairs.
The bond angle from O = C = O is 180° because the geometry is a linear geometry.
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.
