Suppose a 95% confidence interval for μ has been constructed. if it is decided to take a larger sample and to decrease the confidence level of the interval, then the resulting interval width would (assume that the sample statistics gathered would not change very much for the new sample.) a) be larger than the current interval width. b) be narrower than the current interval width. c) be the same as the current interval width. d) be unknown until actual sample sizes and reliability levels were determined.

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.
