Are free to look for explanations for why things have changed.
Answer:
stay the same.
Explanation:
Expansionary monetary policy means that a central bank is using its tools to manipulate the economy. It does that by increasing the money supply, aggregate demand and <em>lowering the interest rates</em>. This type of policy is opposite to the contractionary monetary policy.
On the other side, when government spending increases the budget deficit, the Treasury issues more bonds. This reduces the price of bonds and <em>raise the interest rate</em>. Or in our example, the aforementioned lower interest rate gets back to where it was. This process could lead to disruption in the economy.
Answer:
A species accumulation curve that had leveled off
Explanation:
In sampling, access if the current sampling had adequately assessed the species diversity, species richness is plotted as a function of the sampling effort, that is, each data point on a species accumulation curve represents the total number of individuals and sampling effort up to that point. Species accumulation curves can help us determine when most or all of the species in a community have been observed. A species accumulation curve that had leveled off indicates that you had adequately sampled the species richness of a given community.
Answer:
Accept H0
Explanation:
A group of psychologists was interested in knowing whether living environment had any effect on a student's grade point average (GPA). They took a set of twins and randomly assigned one sibling of the twins to live in an urban area and the other to live in a rural area After one year, they computed the GPAs for the twins and looked at the differences. Then they calculated the test statistic, and the P-value was found to be between 0.20 and 0.25. With a 0.05 level of significance, we should <u>accept</u> H0, and conclude that there is insufficient evidence to suggest that a difference exists between the mean GPAs of the two living environments.
A p value that is less than or equal to 0.05 suggest strong evidence against the null hypothesis, so you reject the null hypothesis. A p-value greater than 0.05 indicates weak evidence against the null hypothesis, so you accept the null hypothesis. In this study, the null hypothesis will be "living environment has no effect on a student's grade point average (GPA)", and since the p value obtained from the study is greater than 0.05, we accept the null hypothesis.
