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.
We have that the time the earthquake occurred is mathematically given as
The <u>earthquake </u>occurred at =7:03:00 pm
<h3>Co-ordinates</h3>
Question Parameters:
A seismic recording station located 4000 <em>kilometers </em>from the epicenter
an earthquake received the first P-wave at 7:10:00 p.m. (h:min:s).
Generally
From t-x diagram, the x axis marks the distance of the <em>station </em>from the epicenter.
Hence we have that the P wave took 7 min to reach the station.
Arrival time of P and S wave is
dt=5 min 40 sec.
Therefore
The <u>earthquake </u>occurred at =7:03:00 pm
The S wave arrived at = 07:15:40 pm.

Answer:
Climate Changes with Latitude. Places located at high latitudes (farther from the equator) receive less sunlight than places at low latitudes (closer to the equator). The amount of sunlight and the amount of precipitation affects the types of plants and animals that can live in a place.
