An experiment on memory was performed, in which 16 subjects were randomly assigned to one of two groups, called "sentences" or "intentional". each subject was given a list of 50 words. subjects in the "sentences" group were told to form multiple sentences, each using at least two words from the list, and to keep forming sentences until all the words were used at least once. subjects in the "intentional" group were told to spend five minutes memorizing as many of the 50 words as possible. subjects from both groups were then asked to write down as many words from their lists as they could recall. we are interested in determining if there is a significant difference in the average number of words recalled for subjects in the "sentences" group vs. subjects in the "intentional" group, using α = 0.05. the data is in the table below. number of words recalled"sentences" group 37 26 29 27 26 29 28 28"intentional" group 32 30 34 31 32 30 33 31a. enter the values for the following statistics: xsentences =ssentences =xintentional =sintentional =(xsentences - xintentional) =standard error of (xsentences - xintentional) =

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.
