Binomial distribution - Study guides, Class notes & Summaries

INSTRUCTIONS FOR QUESTIONS 1-5 For each of the following five questions, select the probability distribution that could best be used to model the described scenario. Each distribution might be used, z ero, one, or more than one time in the five questions. These scenarios are meant to be simple and straightforward; if you're an expert in the field the question asks about, please do not rely on your expertise to fill in all the extra complexity (you'll end up making the questions below more diff...

If five students take Exam 1 and score 81, 85, 89, 93, and 97, what is the variance on Exam 1? - correct answer Determine that the average score is 89 Determine that the differences between each score and the mean are -8, -4, 0, 4, 8 Square all of the differences to get 64, 16, 0, 16, 64 Take the average of the squared differences to get 32 Answer: 32 If five students take Exam 2 and score 83, 83, 84, 94, 96, what is the standard deviation of Exam 2? ...

Explain what we mean by a confidence level (exp. 95%) The percentage of intervals, based on all possible samples of the same size taken from the same population, that contain the parameter. For example, if we construct 100 95% confidence intervals using 100 samples of the same size, approximately 95 of the intervals will contain the true parameter and 5 will not. A point estimate is the value of a _________ that estimates the value of a ____________ statistic, parameter ...

True - The relationship that links the predictors is highly non-linear. - Answer- In Logistic Regression, the relationship between the probability of success and the predicting variables is non-linear. False - In logistic regression, there are no error terms. - Answer- In Logistic Regression, the error terms follow a normal distribution. True - the logit function is also known as the log-odds function, which is the ln(P/1-p). - Answer- The logit function is the log of the ratio of the prob...
