Question

We are interested in estimating the proportion of graduates at a mid-sized university who found a job within one year of completing their undergraduate degree. Suppose we conduct a survey and find out that 347 of the 400 randomly sampled graduates found jobs. The graduating class under consideration included over 4500 students.

(a) Consider the population parameter of interest. What is the value of the point estimate of this parameter? 4500

(b) Check if the conditions for constructing a confidence interval based on these data are met:

np= ____.>= ______
n(1−p)=____ >= _____
The sample observations are ? Independent /Not Independent .
Thus, we may conclude that the conditions ? Are satisfied /Are not satisfied .

(c) Calculate a 94% confidence interval for the proportion of graduates who found a job within one year of completing their undergraduate degree at this university.
