Response of Interest Yes Sample Size 55 Count for Response 38 Sample Proportion Confidence Interval Confidence Coefficient 0.95 Lower Limit Upper Limit Hypothesis Test Hypothesized Value 0.60 Test Statistic P-value (Lower Tail) 0.9156 P-value (Upper Tail) P-value (Two Tail) USA Today surveyed fifty-five working parents and asked them if they feel they spend too little time with their children due to work commitments. The findings were recorded in Excel. On the basis of this sample, have we reason to believe that the proportion of working parents who feel they spend too little time with their children due to work commitments is different from 60% at α=.1? Use the excel output above to answer the following question.
What is the 98% confidence interval for the population percentage of working parents who feel they spend too little time with their children due to work commitments?
a. (0.6111, 0.7707)
b. (0.5688, 0.8130)
c. None of the answers is correct
d. (0.5457, 0.8361)
e. (0.5884, 0.7934)
