The temperature, t, in degrees fahrenheit, can be found by counting the number of cricket chirps, c, heard in 14 seconds and then adding 40. the equation t = c + 40 models the relationship between the temperature and the number of cricket chirps. what is true about the graph that represents this real-world scenario? check all that apply. the graph is continuous. all values of t must be positive. a viable solution is (–2, 38). a viable solution is (0.5, 40.5). a viable solution is (10, 50). a) the graph is continuous. b) all values of t must be positive. c) a viable solution is (–2, 38). d) a viable solution is (0.5, 40.5). e) a viable solution is (10, 50).                                          b & e

The survey of study habits and attitudes (ssha) is a psychological test that measures the motivation, attitude toward school, and study habits of students, scores range from 0 to 200. the mean score for u. s. college students is about 115, and the standard deviation is about 30. a teacher who suspects that older students have better attitudes toward school gives the ssha to 55 students who are at least 30 years of age. the mean score is 113.2. assume the population standard deviation is 30 for older students what is the margin of error for a 95% confidence interval for the population mean score for a. older students? b. compute the 95% confidence interval for the population mean score for older students. c. compute the 99% confidence interval for the population mean score for older students. d. compute the 88% confidence interval for the population mean score for older students.
