At a certain university, 50% of all entering freshmen planned to major in a stem (science, technology, engineering, mathematics) discipline. a sample of 36 freshmen is selected. what is the probability that the proportion of freshmen in the sample is between 0.477 and 0.580?

0.4402

Step-by-step explanation:

Given : The proportion of  the registered voters in a country are Republican = P=0.50

Sample space = 36

The test statistic for proportion :-

For p= 0.477

For p= 0.58

Now, the probability that the proportion of freshmen in the sample is between 0.477 and 0.58 (by using the standard normal distribution table):-

Hence,  the probability that the proportion of freshmen in the sample is between 0.477 and 0.580 = 0.4402
