Suppose that the probability that any random student graduates with honors is 0.07. Also, we know that the probability of a student getting into grad school, given that they graduated with honors is 0.70. The probability of a student getting into grad school, given that they did not graduate with honors is 0.05. What is the probability that a student did not graduate with honors, given that the student did get in to graduate school?

A. 0.0514

B. 0.487

C. 0.513

D. 0.75

Twenty percent of the contestants in a scholarship competition come from Pylesville High School, 40% come from Millerville High School, and the remaining come from Lakeside High School. Two percent of the Pylesville students are among the scholarship winners; 3% of the Millerville contestants and 5% of the Lakeside contestants win. a) If a winner is chosen at random, what is the probability that they are from Lakeside? b) What percentage of the winners are from Pylesville?

Sky High School has significant student dropout and failure rates among its senior-year classes. To address this issue, it has obtained grant funding for the senior class. Because this problem appears to be dispersed across the entire senior class, some elements of the program serve all the seniors, even those who appear successful and on track toward graduation throughout the year. The objective of the program is for the students to complete the senior year and graduate. Success of this retention program is determined to be graduation. The data in the table below are available:

Please provide measures of process and financial measures of efficiency and effectiveness. Is the Sky High School guidance office making progress towards its mission? Why or why not?

4. I sample 200 PCC students to see whether or not they drink coffee at school, and find the confidence interval for the proportion who say they do drink coffee to be (0.65, 0.78) at the 95% confidence level. For the statements below, determine if they are True or False. Make your responses clear and legible!

A. 95% of all students drink coffee between 65% and 78% of the time.

B. We’re 95% confident that the students sampled drink coffee between 65% and 78% of the time.

C. 147 of the students sampled said they drink coffee at school.

D. Between 65% and 78% of the students drink 95% of all the coffee drank at school.

E. 143 of the students sampled said they drink coffee at school.

F. We’re 95% confident that the true proportion of PCC students who drink coffee at school is between 65% and 78%.

G. We’re 95% confident that the interval between 65% and 78% has captured the true proportion of PCC students who drink coffee at school.

H. We’re between 65% and 78% confident that the true proportion of PCC students who drink coffee is 95%.

Thirty five percent of adult Americans are regular voters. A random sample of 350 adults in a medium size college town were surveyed, and it was found that 155were regular voters. Estimate the true proportion with 95% confidence and comment on your results.Write a conclusion for the confidence interval.Round to 3 decimalplaces.

At a company picnic at a state park out of town, a child falls from a tree and fractures her forearm. You give appropriate first aid (RICE), and the parents now will take her to the nearest emergency department.

Should you splint the arm?

If so, describe the steps for doing it.

Find the flaw in the following argument made by a business analyst in a small town: "As the number of rental units has increased in the city, the rent prices have decreased . But a lower price will increase demand for the rental units, pushing the price prices up again”. Provide a short but precise answer!

77 kW is to arrive at a town over two 0.140 ? lines. Estimate how much power is saved if the voltage is stepped up from 240 V to 2400 V and then down again, rather than simply transmitting at 240 V . Assume the transformers are each 99% efficient.
