Neurons fire action potentials (spikes) at different frequencies under different circumstances. in one study, researchers position an awake-behaving monkey so that he or she is looking at a luminous dot 40 cm away, and they record the activity of a single neuron in the monkey's brain to determine the neuron's baseline. over the course of 64 trials randomly interspaced with other conditions, that neuron is found to have an average baseline of x¯=26.8 spikes per second with a standard deviation of =33.2 spikes per second. what is the standard error of the sample mean, se, in spikes per second? give your answer to two decimal places.

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.
