Among the senior class at a high school, 55% of Ms. Keating's students plan on majoring in a branch of STEM, while 49% of Ms. Lewis's students plan on majoring in a branch of STEM. Suppose Ms. Keating chooses 25 of her students at random and Ms. Lewis chooses 23 of her students at random. Since npK, nk (1- Px) and n PL, n (1- PL) are all greater than 10, the Normal condition is met. Let K = the proportion of Ms. Keating's students from the sample who plan on majoring in a branch of STEM, and let L = the proportion of Ms. Lewis's students from the sample who plan on majoring in a branch of STEM. What is the probability that the proportion of students who plan on majoring in a branch of STEM is greater for Ms. Keating? Find the z-table here. 0.338 O0.614 0.662 0.841

A 7th grade science teacher would like to know if spending more time doing class experiments will help his students preform better on tests. In a day, he teaches 4 periods of science, so for his 1st and 3rd period classes, he taught as he normally does with mostly lectures and occassional class experiments. For his 2nd and 4th period classes, he did a class experiment everyday with minimal lectures. There were n=25 different students in each of his classes. He then wanted to compare the exam averages between his classes to see if student preformance was significantly different. Which statistical tests should he use?

A researcher is interested in understanding if there is a difference in the proportion of undergrad and grad students at UCI who prefer online teaching to in person teaching, at the a = 0.05 level. They take 2 samples, first, a sample of 300 undergrad students. The second, is a sample of 172 grad students. Of the undergrads, 186 said they preferred online lectures, and of the graduate students, 104 said that they prefer online lectures. Let p₁ = the proportion of undergrad students who prefer online class and p2 = the proportion of grad students who prefer online lectures.

During the get-together for Gerdau developers, 17 employees sat around a large round table. Each of the collaborators received a paper that said if he should say only the truth or only a lie. During the dynamic performed, each one should say which colleagues were lying and which were telling the truth. At the end of the game, all employees who were participating said: "The two people next to me are liars". At a minimum, how many employees received the paper saying to tell only the truth?
