Data is given on the number of patients who tested positive for COVID-19 on April 5th, 2020 in different cities in Alberta (AB). The following represents the boxplot for this dataset. H O 10 20 30 40 50 60 70 80 90 Fill in the Correct Answer for each Part: Part 1: 25% of cities in AB have fewer than how many positive COVID-19 cases? (1 mark) Part 2: 50% of cities in AB have more than how many positive...
Question 5 Part A Biological macromolecules such as proteins may be positively, negatively, or neutrally charged depending on what amino acids are present. Some parts of a macromolecule may be positively charged while others are negatively charged, and this can affect the conformation - the shape of the macromolecule. Changes in the conformation may affect the function of a macromolecule. Two charged macromolecules (labelled 1 and 2) have charges q1 =+3.20 * 10-19 C and q2 =+12.8 10-19 C. They...
. Exercise 10: To prevent developing a certain type of cancer, Health Canada organize a di- agnostic test. The false positive and negative rates for this diagnostic test are five percent and four percent, respectively. Assume that five percent of the population has this type of cancer. 1. If a randomly selected person has a positive test result, what is the prob- ability that the person has this type of cancer? 2. The test is administrated twice on the same...

1. A certain drug test has a 10% false positive rate (a positive test even if the person has not used that drug) and a 15% false negative rate (a negative test despite the person using the drug). It is known that approximately95% of people do not use the drug being tested for. If 10,000 people are given the test, complete the table with the expected results and then answer the following questions. Test Results Positive Negative Total No Drug...
probabilities I know from given problem: .99 have disease AND Test + therefore... .01 have disease AND Test - .02 do not have disease AND Test + therefore... .98 do not have disease AND Test - .10 of TOTAL population HAVE Disease therefore... .90 of TOTAL population DO NOT HAVE Disease. what I thought I would have to do to get what is being asked is P(have disease | tests +) = P(Have disease AND Test +) / P(test +)...
1. Suppose you roll a special 19-sided die. What is the probability that the number rolled is a "1" OR a "2"? Round to 3 decimal places. 2. A test was given to a group of students. The grades and gender are summarized below A B C Total Male 7 10 2 19 Female 8 5 15 28 Total 15 15 17 47 If one student is chosen at random from those who took the test, Find the probability that...
A negatively charged oil drop whose mass is 10-15 kg and whose charge is -6.4 10-19 Coulombs remains stationary under the influence of the Earth’s gravitational field and a uniform external electric field made by two oppositely-charged parallel plates (see diagram below). Ignore the influence of Earth’s electric field on the oil drop. Determine the magnitude and direction of the net electric field created by the plates (not the electric field of the oil drop !). Explain completely how you...
