Which statement best identifies new evidence that could change that change the history of science?

According to the Merck Veterinary Manual, the average resting heart rate for a certain type of sheep dog is 115 beats per minute

olga nikolaevna [1]

Answer:

C: H0:μ=115, Ha:μ≠115

Explanation:

In statistics, H0 is null hypothesis otherwise known as hypothesis of no difference. Meaning that there is no difference in the observed data or population

Ha is the alternate hypothesis, meaning there is a significant difference in the observed data or population.

In this case, the normal heart rate is 115 bpm. This represents the standard. The observed mean of 118.2 will be statistically compared to 115.

Hence, the hypothesis of no difference (H0) will assume that the observed mean 118.2 is the same is the standard mean, H0:μ=115 while the alternate hypothesis will assume that 118.2 is significantly different from 115, Ha:μ≠115.

Correct option: C

What is stream deposition

Mars2501 [29]

A stream's sediment load is typically deposited, eroded, and redeposited many times in a stream channel, especially during climatic variations such as flooding. Sediments are deposited throughout the length of the stream as bars or floodplain deposits.

A scientist constructs a graph to show the age structure that f the human population of county

DedPeter [7]

Based on the graph, it can be concluded that the population is increasing rapidly because of the youth of the population.

<h3>What is population?</h3>

The population of a species is the number of organisms of the same species found within a given habitat.

Population graphs are used to describe the trend in the population of a given species of organisms.

The factors that affects population growth of a country include:

fertility rates,
mortality rates or life expectancy,
the initial age profile of the population, and
migration

Given the population graph of the country, the conclusion can be drawn is that the population is increasing rapidly because of the youth of the population.

In conclusion, the higher the fertility rate the faster the population growth.
