Question 3: A new virus has been circulating in Townsville. Fortu- nately, a pharmaceutical company called Umbrella Inc. has developed a test for diagnosing - before symptoms appear - individuals who are infected so that they can be preemptively quarantined. The probability an individual is currently infected is . Therefore, the prob- ability he/she is not infected is. If an individual is infected, Umbrella Inc.'s test always reports "VIRUS DETECTED" (i.c. with probability 1), but if an individual is not...

A pharmaceutical company has discovered a new drug, called REJUV, which is claimed to delay the aging process. There are 100 consumers who are interested in this product. The fraction q (with 0 < q < 1) of these consumers are willing to pay up to $15 for it, while the remaining consumers are willing to pay up to $10. The pharmaceutical company is going to sell REJUV in packets to a retailer at a price of $w per packet....
Question 3 (7 marks) A manufacturer has developed a new type of bicycle frame which will be sold with a 2-year warranty. To see whether this is economically feasible, 20 prototype frames are subjected to an accelerated life experiment to simulate 2 years of use. The proposed warranty will be modified only if fewer than 90% of such frames would survive the 2-year period. (a) Let p be the true proportion of frames that survive. Find a rejection region for...
A civil engineer has been studying the frequency of vehicle accidents on a certain stretch of interstate highway. Longterm history indicates that there has been an average of 1.70 accidents per day on this section of the interstate. Let r be a random variable that represents number of accidents per day. Let O represent the number of observed accidents per day based on local highway patrol reports. A random sample of 90 days gave the following information. r 0 1...

Since the 1980s, HIV (Human Immunodeficiency Virus) has been infecting humans around the world causing the condition known as AIDS (Acquired Immune Deficiency Syndrome). HIV, like all viruses, needs to enter cells and use their machinery to reproduce and spread. During HIV infection, the virus enters specific cells of the immune system (T-cells) by "docking" onto cell surface proteins, including one called CCR5 Genetic analysis of individuals who are naturally immune (resistant) to HIV have revealed that resistance to HIV...
i need help on question 3 to 22 please.
Midterm ex review. MATH 101 Use the following information to answer the next four exercises. The midterm grades on a chemistry exam, graded on a scale of 0 to 100, were: 62, 64, 65, 65, 68, 70, 72, 72, 74, 75, 75, 75, 76,78, 78, 81, 82, 83, 84, 85, 87, 88, 92, 95, 98, 98, 100, 100,740 1. Do you see any outliers in this data? If so, how would...
For this project, each part will be in its oun matlab script. You will be uploading a total 3 m files. Be sure to make your variable names descriptive, and add comments regularly to describe what your code is doing and hou your code aligns with the assignment 1 Iterative Methods: Conjugate Gradient In most software applications, row reduction is rarely used to solve a linear system Ar-b instead, an iterative algorithm like the one presented below is used. 1.1...
i need help to understand those two question from discussion
in this artical please.
3. Take a few minutes to re-read the first four paragraphs of the Discussion section. Explain in your own words the "metabolic suppression hypothesis" proposed by the researchers: what is the hypothesis, and why might it be plausible? WRITE YOUR RESPONSE HERE PLEASE (don't forget the in-text citation, as well as quotation marks and a page number if you are quoting in your answer) This study...
