TABLE 11-2 The Dean of a College Is Interested in the Proportion

question 60

Multiple Choice

TABLE 11-2
The dean of a college is interested in the proportion of graduates from his college who have a job offer on graduation day. He is particularly interested in seeing if there is a difference in this proportion for accounting and economics majors. In a random sample of 100 of each type of major at graduation, he found that 65 accounting majors and 52 economics majors had job offers. If the accounting majors are designated as "Group 1" and the economics majors are designated as "Group 2," perform the appropriate hypothesis test using a level of significance of 0.05.
-Referring to Table 11-2 , the hypotheses the dean should use are:

• A) H₀: π₁ - π₂ = 0 versus H₁: π₁ - π₂ ≠ 0.
• B) H₀: π₁ - π₂ ≠ 0 versus H₁: π₁ - π₂ = 0.
• C) H₀: π₁ - π₂ ≤ 0 versus H₁: π₁ - π₂ > 0.
• D) H₀: π₁ - π₂ ≥ 0 versus H₁: π₁ - π₂ < 0.

Describes processes or actions in cells that need adenosine triphosphate for energy.

Concentration Differences

The variance in the amount of a substance in different areas, leading to diffusion from high to low concentration.

Plasma Membrane

The semipermeable membrane surrounding the cytoplasm of a cell, composed of a phospholipid bilayer with embedded proteins.

Concentration Differences

Variations in the amount of a particular substance within a given volume, leading to a gradient that can cause diffusion.
