CONFIDENCE INTERVALS FOR THE DIFFERENCE IN 2 POPULATION MEANS Children in two elementary school classrooms were given two versions of the same test, but with the order of questions arranged from easier to more difficult in Version A and in reverse order in Version B. Randomly selected students from each class were given Version A (sample 1) and the rest Version B (sample 2). The 95% confidence interval for the difference in the average score between students taking Version A and students taking Version B is (-10, -2). Interpret this interval. O u1 is similar to µ2, therefore we can be 95% confident that the average score for students taking Version A is similar to that of students taking Version B. µ1 is substantially more than µ2, therefore we can be 95% confident that the average score for students taking Version A s substantially less than for students taking Version B. µ1 is substantially less than µ2, therefore we can be 95% confident that the average score for students taking Version A s substantially less than for students taking Version B.

In a random sample of 250 high school students, it was found that 85.2% (213) of them later graduated. Find the 95% and 98% confidence interval for the true proportion of all high school students who graduate. Compare the two proportions.
A survey was conducted of visitors to the Jakarta Fair. For this reason, two groups of samples were taken. The first sample was 500 visitors for women and when they were asked 325 people said they were satisfied with the exhibition at the Jakarta Fair, while the second sample consisted of 700 visitors for gentlemen and 300 of them said they were not satisfied with the exhibition at the Jakarta Fair. the Jakarta Fair. Make a 95% confidence interval to estimate how much the difference between the two populations of visitors who are satisfied with the exhibition at the Jakarta Fair?

In a random sample of 392 people that were tested for the Norcovirus, it was found that 314 did not have the virus. A 97% confidence interval was constructed to estimate the proportion of the population that does not have the Norcovirus. This confidence interval came out to be (0.76,0.84).

In an engineering class, students want to determine the difference in the mean strength between two different types of building materials—Type A, which is relatively inexpensive, and Type B, which is slightly more expensive. The students take a random sample of 60 of the Type A building material and a random sample of 27 of the Type B building material. Given the mean strength for each sample, the students construct a 95% confidence interval for the difference in population means. (a) Determine the degrees of freedom for the conservative approach for finding the t critical value. (b) Find the t critical value associated with 95% confidence. (Use a table or SALT. Round your answer to two decimal places.)
