- Randomization is important when assigning the students to the treatment and control groups to ensure A college professor hypothesizes that readers will comprehend more when reading a graphic novel than when reading text with no illustrations. To conduct an experiment, the professor will assign some students to the control group with a reading assignment in paragraph form and other students to the treatment group with a reading assignment in graphic novel form. Afterwards, all the students will take a quiz about the O that both groups are made up of students from the same class. O that the treatment group has more students to better test the hypothesis. O that each student does not know about the alternative version of the assignment. reading. O that both groups are roughly equivalent with regards to students' gender, reading ability, and study habits.

It was found that, among a random sample of 79 couples at the fair with their children, 44 had visited the new miniature golf course, and among an independently chosen, random sample of 70 couples at the fair on a date (without children), 23 had visited the miniature golf course. Based on these samples, can we conclude, at the 0.01 level of significance, that the proportion p, of all couples attending the fair with their children who visited the miniature golf course is different from the proportion p₂ of all couples attending the fair on a date who visited the miniature golf course? Perform a two-tailed test. Then complete the parts below. Carry your intermediate computations to three or more decimal places and round your answers as specified in the parts below. (If necessary, consult a list of…
- Twenty university students chosen at random from students enrolled at Carthage College took part in an experiment testing the effect of watching ABC News versus CNN on knowledge of world events. The 20 participants were divided randomly into two equal groups of 10 students each. One group was assigned to watch ABC and the other was assigned to watch CNN. Participants then watched their assigned station (ABC or CNN) for 3 hours a night for 4 weeks. At the end of the 4 week period they were administered a test of world knowledge. The results were as follows: XbarABC = 104; sABC = 12 XbarCNN = 99; sCNN = 10 Compute the 95% confidence interval around the difference between the two groups.In a large clinical trial, 401,476children were randomly assigned to two groups. The treatment group consisted of 202,144 children given a vaccine for a certain disease, and 29 of those children developed the disease. The other 199,332 children were given a placebo, and 113 of those children developed the disease. Consider the vaccine treatment group to be the first sample. Identify the values of n1, p1, q1, n2, p2, q2, p, and q. n^1=Need all of them not just n1 please

The treatment group consisted of 201,186 children given a vaccine for a certain disease, and 30 of those children developed the disease. The other 200,135 children were given a placebo, and 100 of those children developed the disease. Consider the vaccine treatment group to be the first sample.
