Asked Oct 7, 2019

suppose that 60% of all students currently enrolled at all California Community College campuses combined are female. Researchers want to do a survery, and randomly select 1000 students who are currently enrolled at CSU campuses. **Let P represent the proportion of students in the sample who are female.**

d. find the probability that more than 65% in the sample are female. Use the distribution P

e. find the probability that between 56% and 64% in the sample are female. Use the distribution P

f. repreat part (e), but use the Normal approximation to the binomial without making the continuity correction. Show your calculator input and calculations or reasoning

Step 1

It is provided that *P* is defined as the proportion of students in the sample who are female. The proportion of females, who are enrolled in California Community college campuses, is 60%.

Step 2

d)

The probability, that more than 65.00% of the students in the sample are females, can be calculated as:

Step 3

e)

The probability, that more than 56.00% and less than 64.00% of the...
