In a survey 163 of 388 administrative professionals responded that verbal recognition is the most preferred form of recognition, and 74 responded that cash bonuses are most preferred. a. Construct a 95% confidence interval estimate for the population proportion of administrative professionals who prefer verbal recognition. b. Construct a 95% confidence interval estimate for the population proportion of administrative professionals who prefer cash bonuses. c. Interpret the intervals in (a) and (b). d. Explain the difference in the results in (a) and (b).

Step 1
To construct a 95% confidence interval estimate for the population proportion of administrative professionals who prefer verbal recognition, we will use the formula: CI = p-hat ± Z * sqrt((p-hat * (1-p-hat)) / n) where p-hat is the sample proportion, Z is the Show more…

Use the sample data and confidence level. In each case, a) find the best point estimate of the population proportion p b) identify the value of the margin of error E c) construct the confidence intervals d) write a statement that correctly interprets the confidence interval In a study of a cell phone use and brain hemispheric dominance, and Internet survey was e-mailed to 5000 subjects randomly selected from an online group whose focus is related to ears. 717 surveys were returned.
