Yes 35 42 63

No 91 104 65

The percentage of the undergraduates surveyed who major in Engineering is 36.5%

Step-by-step explanation:

Given: The above table

Required: Percentage of undergraduates that majored in Engineering

We'll solve this question irrespective of whether the undergraduate student plans to go to a graduate school or not.

Follow the steps below

Step 1: Calculate the total engineering students

Tot Engineering students = Undergraduate student that plan to go to graduate school + those that have no plans for graduate school

From the engineering column

Undergraduate student that plan to go to graduate school = 42

those that have no plans for graduate school = 104

Total = 42 + 104

Total = 146

Step 2: Calculate percentage of this category of undergraduates

Percentage is calculated as a ratio of required population to total population.

In other words,

Percentage = Required Population ÷ Total Population

Here,

Required population = total engineering students

Required population = 146

Total Population = 400

Percentage = 146/400

Percentage = 0.365

Percentage. = 36.5%

Hence, the percentage of the undergraduates surveyed who major in Engineering is 36.5%
