in a town, 55% of people do sports and 40% paint. 45% of the people in this town are not interested in such activities at all. Since it is known that a person chosen randomly from the town does sports, what is the possibility of this person painting at the same time?

Solution :

Let us define some events as follows :

A : A randomly selected person does sports

B : A randomly selected person does paint

We have following informations :

P(A) = 55/100 = 0.55

P(B) = 40/100 = 0.40

45% of the people in this town are not interested in such activities at all.

We have to obtain P(B | A).

Let's take .

Hence, the required probability is 0.7273.

Suppose that the fraction of infected people in a city is p = 0.01. 100 people from the city board a small cruise. You can assume that the people are unrelated to each other and randomly chosen so that each person is infected independently with probability p. You can also ignore the possibility that they infect each other while boarding. Suppose that the virus test gives negative when the person has the virus with probability 0.2, and gives negative when...

Survey 40 people and ask them this question: “How many days a week do you typically exercise?” You calculated your average for the results, and standard deviation and standard error. The following are your results: Average: 4.8625 Standard Deviation: 1.1602 Standard Error: 0.1834 You then ask a friend what they think the average value is for a person who typically exercises during the week. Your friend claims the average to be 4. 1. What are the appropriate null and alternative...

Does participation in sports, cultural groups, and youth groups improve self esteem for adolescents? What do you think? A study done by McGee et al. (2006) claims that involvement in these groups does improve self-esteem. Following the steps for statistical hypothesis testing, you embark on an independent investigation. For your study, you have randomly selected 100 adolescents with a history of group participation and give them a standardized self-esteem questionnaire. The sample of group-participation adolescents scored a mean of 46.1...

Suppose we are interested in how well people do on a standardized test when they take it for a second time. In a random sample of 400 students who took the test for a second time, students gained an average of X-bar = 12 points. Let’s say that the sample comes from a population with σ = 42. The 95% confidence interval for μ (the mean point gain) is: μ = 12 ± (1.96) (42/√400) = 12 ± 4.12 =...

Inductive generalizations have this form:1. X percent of the observed members of group A have property B. (the sample)2.Thus, about X percent of A have property B. (the generalization from the sample)For instance: 1. 40% of the pickles you have pulled out of the barrel are very good.2.Therefore, about 40% of the pickles in the barrel are very good.To assess the strength or weakness of inductive generalizations (arguments which generalize from sample sets), logicians run through 3 checks: CHECK #1:...
