Homework 3 Probability 1. As part of a Pick Your Prize promotion‚ a store invited customers to choose which of three prizes they’d like to win. They also kept track of respondents’ gender. The following contingency table shows the results: | MP3 Player | Camera | Bike | Total | Men | 62 | 117 | 60 | 239 | Woman | 101 | 130 | 30 | 261 | Total | 163 | 247 | 90 | 500 | What is the probability that: a. a randomly selected customer would pick the camera? 247/500= 0.494=

the following few days they would be getting a lot of practice with this. Students generally stay motivated and less anxious from the beginning if they know they’ll have time to review new material. Stephen Krashen proposed the “Affective Filter Hypothesis” in the 1970s‚ which proposed that certain emotions such as anxiety‚ self-doubt‚ and mere boredom interfere with the process of acquiring a second language (Hadley‚ 62)."

Howbeit‚ Darwin retained within his science a hypothetico-deductive method that formulated a hypothesis which created testable experiments on an empirical scale. As well as‚ Darwin understood that hypotheses allowed for the interaction between the development of creative predictions and viability of these ideas by critical testing. Even though‚ a

What is a possible hypothesis for this study? Samantha believes the E-Z program will help improve the student’s grades. Samantha made a formal prediction about the relationship between the students and the new reading program. The hypothesis she made is a testable theory that will prove the results of the program (Burger‚21) Whose class is a control group and why? Mrs. Brown’s class will be the control group. Mrs. Brown’s class did not receive the new reading program. The control group are the

countable set is given‚ any other set which can be put into a one-to-one correspondence with is also countable. Countably infinite sets have cardinal number aleph-0. While on the other hand‚ continuously infinite numbers‚ also known as continuum hypothesis‚ proved by the German mathematician Georg Cantor‚ states that there is no infinite set with a cardinal number between that of the "small" infinite set of integers and the "large" infinite set of real numbers (the "continuum").

Hypothesis Contrary to Fact Since the first man walked this earth‚ we have been trying to understand why everything is the way it is. Why do things work the way they do? What happens if you put this with that? Humans have always been determined to learn and understand everything they can. As a result‚ the knowledge that beings have acquired and the patterns in subjects have come to be facts. These facts show the definite ways that objects‚ persons‚ and events function. After studying‚ one can

Efficient market hypothesis (EMH)‚ first promulgated by Eugene F. Fama (1970)‚ suggests that financial markets price assets precisely at their intrinsic worth given all publicly available information. Though several empirical works strongly confirm market efficiency‚ some of the hypotheses do not agree with the efficient market hypothesis‚ such as behavior finance hypothesis. This essay will discuss the assumption of efficient market hypothesis and implications when these assumptions do not hold

QUESTION 1 Most of the research on input has developed from Stephen Krashen’s Input Hypothesis. According to the Hypothesis‚ for L2 acquisition to take place‚ the learner must be exposed to comprehensible input. In other words‚ Krashen answers the question about what mechanisms exist to allow learners to acquire a second language. He reaches a conclusion‚ stating that learners can achieve acquisition “by understanding messages‚ or by receiving comprehensible input.” Furthermore‚ the input must contain

therefore‚ it is relatively easy to see their heart under a microscope‚ which makes it easier to count the number of heartbeats‚ thus‚ making my results more accurate. Hypothesis- Their will be a positive correlation between the concentration of caffeine given to the Daphnia and its heart rate. My reason behind this hypothesis is based on the fact that caffeine affects the heart rate of humans‚ as it is a stimulant. From this‚ I can assume that it also affects the heart rate of Daphnia and
