A study asked respondents, "If ever married, how old were you when you first married?" The results are summarized in the technology excerpt that follows. Complete parts (a) through (d) below. One-Sample T: AGEWED Mean StDev SE Mean Variable 95.0% CI AGEWED 26790 23.070 4.991 0.030 (23.010, 23.130) Click the icon to view the table of critical t-values. E= 0.06 (Type an integer or a decimal. Do not round.) (b) Interpret the confidence interval, O A. One can be 95% confident that the mean age of people when first married is 23.070 years. O B. One can be 95% confident that the mean age of people when first married is between 23.010 and 23.130 years. O c. There is a 95% probability that the mean age of people when first married is 23.070 years. O D. There is a 95% probability that the mean age of people when first married is between 23.010 and 23.130 years. (c) Verify the results by computing a 95% confidence interval with the information provided. Begin with the lower bound. 4.991 (Round to three decimal places as needed.)
