researchers at a university studied children born with an infection called roseola. the children also have the causative herpesvirus inserted into their chrome osmoses. At least one parent of each child had the virus in a chromosome of a sampled hair cell. How did the children like;y become infected? and What does the transmission of the viral DNA from generation to generation reveal about the structure of DNA and its replication?

A large boat with 91.44 m in length and 42.672 m in width is carrying 1,360,777.11 kg of coal along the river with a 2.7432m draft (the height from waterline to bottom of the boat). What is the draft and weight of the boat when the boat is empty (no coal)? What is the draft and weight of the boat if the boat hits a wave and looses 10 tons of coal? Treat the boat as a rectangular cylinder. Use university introductory physics techniques.

Historically, 20% of graduates of the engineering school at a major university have been women. In a recent, randomly selected graduating class of 210 students, 58 were females. Does the sample data present convincing evidence that the proportion of female graduates from the engineering school has shifted (changed)? Use α = 0.05. Determine what type of error (Type I or II) could be made in the question above.

A survey of 300 students is selected randomly on a large university campus. They are asked if they use a laptop in class to take notes. Suppose that based on the survey, 135 of the 300 students responded "yes."
a) What is the value of the sample proportion p^?
b) What is the standard error of the sample proportion?
c) Construct an approximate 95 confidence interval for the true proportion p by takingplus or minus 2 SEs from the sample proportion.

In chapter 8 we can see how the course of both Weses' lives have gone in completely different directions. Author Wes is accepted at a prestigious university and receives a scholarship. Other Wes sentenced to life in prison. What do you think was Author Wes Moore's purpose in writing this book? What evidence do you have from the book to back up your answer?

Here is your chance to analyze an actual co-worker conflict situation and make suggestions on how to positively resolve this issue.
The #1 people issue I have is with a younger employee who has been speaking over me in meetings with external vendors.
I approached one of my co-workers to ask if they noticed it as well and they said of course - they were actually angrier than I was.
During the next few meetings, I attempted different techniques to see if she'd notice she was talking over me but it was still happening. Eventually, I pulled her aside and told her the issue I was having with her during meetings and explained it made us look unprofessional.
It worked for a few months but she ended up going back to her old ways. From then on, whenever she spoke over me in meetings, I would stop talking immediately and let her finish her sentence.
Sometimes she got flustered and would look back to me to finish up her thoughts but I wouldn't cut in.
I hope it reflected negatively on her, and not myself or the company.
WANT LONG PARAGRAPH FOR EACH. PLEASE DONT COPY FROM PREVIOUS QUESTION OR INTERNET. THANKS

Answer the following:
In: Computer Science
Every morning the foreman flips a coin to decide which group of planters get first choice of the day's planting sites. You think the foreman doesn't like your group (we won't go into the reasons why, but your suspicions are well-founded) and that he's rigging the coin tosses against your group. You keep track for 12 days and note that 10 of the 12 coin tosses have gone against your group. Test the hypothesis (at α=.05) that the foreman is rigging the coin tosses.

a.Your brother is saving for his daughter (3‐year‐old Monica) to start college in exactly 15 years (t=15) from today (t=0). A single year of college today (t=0) would cost him $25,000. If college costs increase at an annual rate of 3.5%, what will each year of college cost for the four years his daughter is in college (t=15 – age 18, t=16 – age 19, t=17 – age 20, and t=18 – age 21)?
b. University offers your brother the option of signing a contract to pay for all four years of college at once on the day Monica begins college (t=15 at her age of 18). What is the present value of all the college costs you calculated above (all 4 years) when Monica is 18 (t=15) if the University uses a 7% discount rate of return? Hint: Find the present value of college costs from #3 above ... you can't just add them up as they occur at different points in time on the timeline.

Listed below are student evaluation ratings of courses, where a rating of 5 is for "excellent." The ratings were obtained at one university in a state. Construct a confidence interval using a 99% confidence level. What does the confidence interval tell about the population of all college students in the state?
3.5, 2.8, 3.9, 4.6, 3.1, 4.4, 3.5, 4.6, 4.8, 4.3, 4.3, 3.9, 3.1, 3.8, 3.9
What is the confidence interval for the population mean mu? (Round to two decimal places as needed.)
What does the confidence interval tell about the population of all college students in the state? Select the correct choice below and, if necessary, fill in the answer box(es) to complete your choice.
A. The results tell nothing about the population of all college students in the state, since the sample is from only one university.
B. We are 99% confident that the interval from nothing to nothing actually contains the true mean evaluation rating. (Round to one decimal place as needed.)
C. We are confident that 99% of all students gave evaluation ratings between nothing and nothing. (Round to one decimal place as needed.)
