Budget lapsing at army hospitals. Budget lapsing occurs when unspent funds do not carry over from one bugeting period to the next. Refer to the Journal of Management Accounting Research (Vol. 19,2007) study on budget lapsing at US. Army hospitals, Exercise 2.111 (P.99). Because budget lapsing often leads to a spike in expenditures at the end of the fiscal year, the researchers recorded expenses per full-time equivalent employee for each in a sample of 1,751 army hospitals. The sample yielded the following summary statistics: x = $6,563 and s = $2,484. Estimate the mean expenses per full-time equivalent employee of all US. Army hopitals using a 90% confidence interval. Interpret the result. 6,663 + - 97.85

Since opening night, attendance at play a has increased steadily, while attendance at play b first rose and then fell. equations modeling the daily attendance y at each play are shown below, where x is the number of days since opening night. on what day(s) was the attendance the same at both plays? what was the attendance? play a: y = 8x + 191 play b: y = -x^2 + 26x + 126 a. the attendance was never the same at both plays. b. the attendance was the same on day 5. the attendance was 231 at both plays on that day. c. the attendance was the same on day 13. the attendance was 295 at both plays on that day. d. the attendance was the same on days 5 and 13. the attendance at both plays on those days was 231 and 295 respectively.
