Answer: Option 'a' is correct.
Step-by-step explanation:
Since we have given that
Percentage of students in the class of 2013 has done an internship during their time as an undergraduate student = 38% = p₀
Number of architecture majors = 100
We need to check that whether students at her university had an internship rate that was higher than the national average.
Proportion for her university = 43% = p₁
Here, n = 100
Since n > 30.
so, we can use z-test.
Z-test is generally use to identify whether two means are different when the standard deviation is given.
Hence, it is safe to use the z-test for p.
Therefore, option 'a' is correct.
