The following data show the number of paid vacation days for a random sample of 20 workers from this country. Complete parts a through c below. a. Construct a 95% confidence interval to estimate the average number of paid vacation days for workers from this country. The 95% confidence interval to estimate the average number of paid vacation cays for workers from this country is from days to days. (Round to two decimal places as needed.)

Explanation / Answer

For the given data, n = 20, std. dev. = 13.24
t-value = 2.093

= 19.63 +/- 2.093*13.24/sqrt(20)

= (13.4336, 25.8264)
