ume that adults were randomly selected for a poll. They were asked if they "favor or oppose using federal tax dollars to fund medical research using stem cells obtained from human embryos." Of those polled, 485485 were in favor, 396396 were opposed, and 123123 were unsure. A politician claims that people don't really understand the stem cell issue and their responses to such questions are random responses equivalent to a coin toss. Exclude the 123123 subjects who said that they were unsure, and use a 0.100.10 significance level to test the claim that the proportion of subjects who respond in favor is equal to 0.50.5. What does the result suggest about the politician's claim? Identify the null and alternative hypotheses for this test. Choose the correct answer below. A. Upper H 0H0: pequals=0.50.5 Upper H 1H1: pgreater than>0.50.5 B. Upper H 0H0: pequals=0.50.5 Upper H 1H1: pnot equals≠0.50.5 C. Upper H 0H0: pnot equals≠0.50.5 Upper H 1H1: pequals=0.50.5 D. Upper H 0H0: pequals=0.50.5 Upper H 1H1: pless than<0.5

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.
