An experiment was done to see whether open-book tests make a difference. A calculus class of 48 students agreed to be randomly assigned by the draw of cards to take a quiz either by open-notes or closed-notes. The quiz consisted of 30 integration problems of varying difficulty. Students were to do as many as possible in 30 minutes. The 24 students taking the exam closed-notes got an average of 15 problems correct with a standard deviation of 2.5. The open-notes crowd got an average of 12.5 correct with a standard deviation of 3.5. Assume that the populations are approximately normal. At the 5% significance level, does this data suggest that differences exist in the mean scores between the two methods?

(JAVA) Write a program that maintains student test scores in a two-dimesnional array, with the students identified by rows and test scores identified by columns. Ask the user for the number of students and for the number of tests (which will be the size of the two-dimensional array). Populate the array with user input (with numbers in {0, 100} for test scores). Assume that a score >= 60 is a pass for the below.
Then, write methods for:

Computing the number of tests that each student passed

Computing the number of students passed for each test

The methods should accept a two-dimensional array as one argument and a specific student number (for (a)) or a specific test number (for (b)) as the other argument. The methods should return the relevant counts.
Call the above methods (from main) by passing the two-dimensional array that contains the test scores, for each student (for (a)) and then for each test (for (b)). Print the counts.

ath & Music (Raw Data, Software Required):
There is a lot of interest in the relationship between studying music and studying math. We will look at some sample data that investigates this relationship. Below are the Math SAT scores from 8 students who studied music through high school and 11 students who did not. Test the claim that students who study music in high school have a higher average Math SAT score than those who do not. Test this claim at the 0.05 significance level.

Below are data for the number of students in each of four age groups that are enrolled in several local schools:

Using the included data file and SPSS, create a separate Pie Chart of the age groups for each school. Which school has the largest percentage of pre-adolescents? Then create of Bar Graph of the total count of students in each age group that are enrolled in local schools (including the local International School). Which age group represents the largest percentage of local students?

Mr Ahuja have always been interested in whether or not where a student sits is related to the students overall grades in school. Below is a table that divides students into 3 seating areas: Front, Middle, and Back with their given GPAS.

Front Middle Back

3.062 2.859 2.583

3.894 2.639 2.653

2.966 3.634 3.09

3.575   3.564 3.06

4   2.115 2.463

2.69 3.08 2.598

3.523 2.937 2.879

3.332 3.091 2.926

3.885 2.655 3.221

3.559 2.526 2.646

Calculate a One-Way ANOVA table (using EXCEL) for the data above. Complete the following: At α = .05, test to see if there is a significant difference among the average GPA of all the students based on three areas of seating. Use both the critical and p-value approaches. Include hypotheses, critical values, results, and conclusions in the language of the problem.

A growing body of research offers guidance about how to design tasks and structure classroom interactions to support students’ development of and engagement in self-regulated learning. This research indicates that students develop academically effective forms of self-regulated learning and a sense of efficacy for learning when teachers involve them in complex, meaningful tasks that extend over long periods of time. Further development occurs if teaching incorporates these features: student control over their learning processes and products (choices), involvement in self-monitoring and self-evaluation, and opportunities to work in collaboration with peers and seek feedback from them. Mr. LeBlanc, in designing a unit on crustaceans, has planned complex, meaningful tasks for his students to do over a 3-week period to meet learning goals in science. How might he incorporate the other 3 features for promoting self-regulated learning?

1. To make solutions for the Beer's Law graph, you are provided with a 49.9 ppm Allura Red solution. You pipet 10.00 mL of this solution into a test tube and then you pipet 20.00 mL of deionized water into the same tube. After stirring, what is the Allura Red concentration of the new solution you've made? This is Allura Red Dilution 1.

2. If you pipet 10.00 mL of the solution you made in Question #1 into a test tube and then you pipet 10.00 mL of deionized water into the same tube. After stirring, what is the Allura Red concentration of the new solution you've made? Hint: use at least 2 extra significant figures from your answer to question #1 to calculate this answer to avoid rounding errors. Your final answer will be reported to the correct number of sf.
