A television station wishes to study the relationship between viewership of its 11 p.m. news program and viewer age (18 years or less, 19 to 35, 36 to 54, 55 or older). A sample of 250 television viewers in each age group is randomly selected, and the number who watch the station’s 11 p.m. news is found for each sample. The results are given in the table below. Age Group Watch11 p.m. News? 18 or less 19 to 35 36 to 54 55 or Older Total Yes 37 46 59 83 225 No 213 204 191 167 775 Total 250 250 250 250 1,000 (a) Let p1, p2, p3, and p4 be the proportions of all viewers in each age group who watch the station’s 11 p.m. news. If these proportions are equal, then whether a viewer watches the station’s 11 p.m. news is independent of the viewer’s age group. Therefore, we can test the null hypothesis H0 that p1, p2, p3, and p4 are equal by carrying out a chi-square test for independence. Perform this test by setting α = .05. (Round your answer to 3 decimal places.)…

Use the given categorical data to construct the relative frequency distribution. Natural births randomly selected from four hospitals in a highly populated region occurred on the days of the week (in the order of Monday through Sunday) with the frequencies 54, 65, 68, 56, 59, 43, 55. of the week with equal frequency? Construct the relative frequency distribution. Day Relative Frequency Monday % Tuesday % Wednesday % % Thursday Friday % Saturday % Sunday (Type integers or decimals. Round to two decimal places as needed.) Does it appear that such births occur on the days

Last school year, the student body of a local university consisted of 20% freshmen, 21% sophomores, 29% juniors, and 30% seniors. A random sample of 300 students taken from this year's student body showed the following number of students in each class. Freshmen 84 Sophomores 65 Juniors 86 Seniors 65 We are interested in determining whether there has been a significant change in the distribution of class between the last school year and this school year.If the distribution is the same as the previous year, the expected number of freshmen is _____. a. 84 b. 87 c. 60 d. 20
(Using sets) In a study carried out with 260 university students, the following data was obtained: - 64 had taken a math course- 94 had taken a computer science course- 58 had taken a business administration course- 28 had taken a math course and a business administration course- 26 had taken a math course and a computer science course- 22 had taken a computer science course and a business administration course- 14 had taken all three types of courses a. How many students whose records were reviewed had not taken any of the three types of courses?b. Of the students whose records were studied, how many had taken only one computer science course?
