In a recent year, the Better Business Bureau settled 75% of complaints they received. You have been hired by the Bureau to investigate complaints this year involving computer stores. You plan to select a random sample of complaints to estimate the proportion of complaints the Bureau is able to settle. Suppose your sample size is 141. What is the probability that the sample proportion will be at most 4 percent more than the population proportion? (Enter your answer as a number accurate to 4 decimal places.)
1.If the probability of success (P) is 0.70 (70%), then What is the probability of failure? What are the odds?
A sample of 2500 patients were taken to assess a medical test. 40% of the sample had a positive test, 563 patients have the disease and tested negative, and 235 patients do not have the disease and tested positive. What is the probability someone has a positive test if it is known they do have the disease? (round your answer to 4 decimal places) What is the probability someone does not have the disease if their test is known to be negative? (round your answer to 4 decimal places)
2 questions, first one is (a) and the second one is (b)
If the probability that the Islanders will beat the Rangers in a game is 5/6, what is the probability that the Islanders will win at least five out of six games in a series against the Rangers? Round your answer to the nearest thousandth.
If you fail to reject the null hypothesis at the 5% level, then the probability that you are wrong is always 5%.
If the probability that the Islanders will beat the Rangers in a game is 81%, what is the probability that the Islanders will win at least three out of five games in a series against the Rangers? Round your answer to the nearest thousandth.
Suppose you are conducting a test of significance to try to determine whether your cat, Hope, will go to the correct object (out of two) when it is pointed to. You test Hope 100 times and finds she goes to the correct object in 70 out of those 100 trials. In this scenario, what is the variable? Whether or not Hope goes to the correct object The 100 trials The proportion of the 100 trials that Hope goes to the correct object The long term proportion (probability) that Hope will go to the correct object
In a recent year, the Better Business Bureau settled 75% of complaints they received. You have been hired by the Bureau to investigate complaints this year involving computer stores. You plan to select a random sample of complaints to estimate the proportion of complaints the Bureau is able to settle. Suppose your sample size is 299. What is the probability that the sample proportion will be at least 5 percent more than the population proportion?
Does this answer look like I calculated correctly. The question is in a certain population of women 4% have had breast CA, 20% are smokers, and 3% are smokers and have had breast CA. A woman is selected at random from the population. What is the probability that she has had breast CA or smokes or both.
Last year the average math SAT score for students at one school was 775. the Headmaster introduced new methods hoping to improve scores. this year , the math mean SAT score for a sample of students was 1178. If the teaching had no effect, there would be roughly a 3 in 100 chance of seeing such an increase. Does the result have STATISTICAL significance? does the result have PRACTICAL significance? exlain your answer
The next set of problems are the probability problems from the handout, #'s 1, 2, and 3. Make sure to show all your work for them so you can get partial credit if you get it wrong. Round them off to three decimal places (like .256) One study says that 23% of adults in the US use some form of marijuana regularly. If you randomly select 5 people, what is the probability that none of them use marijuana?
