Suppose 80% of all farms in a certain state produce corn. A simple random sample of 60 the state's farms is drawn. (Use technology. Round your answers to three decimal places.) Find the probability that the number of farms producing corn is between 40 and 50, inclusive. That is, find P(40 ≤ x ≤ 50).

Suppose you draw a random sample of 8 first year masters students and find that their ages are 24, 29, 31, 29, 28, 28, 26, 32, respectively; and you draw a random sample of 6 second year masters students and find their ages are 33, 31, 26, 27, 28, and 30, respectively. Assume age is normally distributed in both populations with equal variance. Construct 95% confidence interval for the difference in mean ages of first and second year students.

2. The random variable X denotes the average cost of out-of-state tuition with a mean of $25,600 and a variance of 1,000,000, i.e .X ∼ N ( 25 , 600 ; 1 , 000 , 000 ).    If a random student is chosen in the US what is the probability their out of state tuition is greater than $24,100? 2B) What is the probability that a random out of state student has out-of-state tuition greater than 25,000 and less...

Research question: Amongst all Penn State students, do traditional-age students and adult learners differ in terms of their grade point averages (GPA)? Researchers are going to collect data from 1,000 Penn State students. They will call each student to ask whether they identify as a traditional-age student or as an adult learner. They will also ask each student for their GPA (scale of 0 to 4.0). 9. Describe how researchers could use a convenience sampling method to obtain a sample...

Suppose that a random sample 80 recent graduates of students is taken and it is found that 30 of them participated in an undergraduate research project while at school. a) Find a 99% confidence interval for the population proportion of students who participate in undergraduate research while at school. b) Using the fact that 30 out of the 80 graduates participated in undergraduate research, how large a sample of graduates is needed to arrive at a 99% confidence interval with...

The age of a students in a class is a normal random variable. There are 80 students in our class. I select 9 students randomly and calculate the mean of their ages (sample mean). I repeat this experiment 1,000,000 times. Then I calculate the mean and standard deviation of the 1,000,000 sample means that I measured; the calculated values are 22 and 4, respectively. What is the probability that the age of a randomly selected student in the class is...
