Answer:

H0:p1 − p2 = 0 and Ha:p1 − p2 ≠ 0

Explanation:

Null hypothesis would be there not being a difference, so the difference would be 0.

Alternative hypothesis would be that there is a difference. However, the president of the university does not want to determine whether more males than females, or more females than males, get a GPA of 3.5 or higher, so the alternative hypothesis is =/= 0.

Kryger [21]

Answer:

C. [-1, 0, 1]

Explanation:

Required: Which list do not return the intended result

From the question, we understand that the procedure will return true for a list that contains all positive.

Using this as a point of reference, option (D) will return true because 1, 2 and 3 are all positive numbers.

Similarly, options (a) and (b) will return false because they do not contain positive numbers

Lastly, option (c) will not return the required result because it contains positive and negative numbers

<em>Hence, option (c) answers the question.</em>

RideAnS [48]

Industrialized countries have a greater capacity to produce goods and services than other countries.

Industrialization is a term that refers to the production of goods and services. Industrialization is related to the development of new technologies and machines to optimize production processes.

According to the above, more developed countries have a greater capacity to produce goods and services, such as the United States, Russia, Japan, and China, because much of its economy is based on the production of services and goods. On the other hand, less developed countries (also known as developing or underdeveloped countries) do not yet have a high capacity to produce goods and services. On the contrary, their economies are based on other fields such as agriculture or resource extraction.
