A publisher reports that 67% of their readers own a personal computer. A marketing executive wants to test the claim that the percentage is actually over the reported percentage. A random sample of 160 found that 71% of the readers owned a personal computer. Is there sufficient evidence at the 0.01 level to support the executive's claim?

- In light of the fact that research always contains the possibility of error, we have to be careful not to present research results as causal relationships when they are only correlations. And yet, sometimes correlation is used. For example, in car insurance, male drivers are correlated with more accidents, so insurance companies charge them more. It would be impossible to actually test this for causation. Given the above, how do we balance this possibility of error with the need to have statistical results to inform our business decisions?arrow_forwardGiven two independent random samples with the following results: n1=441 x1=185 n2=560 x2=351 Can it be concluded that there is a difference between the two population proportions?

- Interpret the coefficients of your regression model. Specifically, what does the fixed component of the model mean to the consulting firm? Interpret the fixed term, b 0b0, if appropriate. Choose the correct answer below. A. It is not appropriate to interpret b 0b0, because its value is the predicted billable hours for overhead costs of 0 dollars, but the firm cannot have overhead costs of 0 dollars associated with a client. B. The value of b 0b0 is the predicted overhead costs for 0 billable hours. C. It is not appropriate to interpret b 0b0, because its value is the predicted overhead costs for 0 billable hours, but someone with 0 billable hours would not actually be a client of the firm. D. For each increase of 1 unit in billable hours, the predicted overhead costs are estimated to increase by b 0b0. E. The value of b 0b0 is the predicted billable hours for an overhead cost of 0 dollars. F.

Choose all that apply. Including propensity score estimates as a predictor in a regression model on outcomes can help resolve imbalance between treatment and control groups for covariates used in the propensity score model Standard diagnostic tools for binary prediction or classification models (e.g. logistic regression or classification trees) are similarly used in evaluating propensity score estimates When conditional ignorability holds given the observed covariates, then the treatment assignment will also be ignorable conditioned on the propensity scores Overfitting in propensity score estimation can achieve more efficient estimates of treatment effects than using propensity score estimates that are closer to the true propensities Unlike full matching, subclassification, and weighting methods, nearest neighbor matching does not necessarily use all…arrow_forward

This is a moot point because coefficient significance is not really important B. Whine and complain about it to your work colleagues C. Live with a less powerful test for significance D.
