MATH 225N Week 6 Confidence Intervals Questions and Answers (Chamberlain College of Nursing). 1) On a busy Sunday morning, a waitress randomly sampled customers about their preference for morning beverages, specifically, she wanted to find out how many people preferred coffee over tea. The proportion of customers that preferred coffee was 0.42 with a margin of error 0.07. Construct a confidence interval for the proportion of customers that preferred coffee. (0.42 - 0.07), (0.42 + 0.07) = (0.35...

Using the data set you collected in Week 1, excluding the super car outlier, you should have calculated the mean and standard deviation during Week 2 for price data. Along with finding a p and q from Week 3. Using this information, calculate two 95% confidence intervals. For the first interval you need to calculate a T-confidence interval for the sample population. ........CONTI...........

Consider when businesses might use confidence intervals to estimate values, such asin sales projections, marketing results, and so forth. Describe a business decision thatcould be helped with confidence intervals. Be specific! Then create a problem withnumbers from which another student could calculate a confidence interval and make adecision.

MATH302 Week 5 Discussion; Confidence Intervals and Sample Size

α: - ANSWER-The symbol for level of significance (probability of a type I error). Alternative Hypothesis - ANSWER-The hypothesis that the researcher wants to prove or verify; a statement about the value of a parameter that is either "less than," "greater than," "not equal to." β: - ANSWER-The probability of failing to reject a false null hypothesis (probability of a type II error). Confidence Interval - ANSWER-An estimate of the value of a parameter in interval form with an a...
