Students completed a high school senior level standardized algebra exam. Major for students was also recorded. Data in terms of percent correct is recorded below for 32 students. We are interested to see if there is any difference between students' high-school algebra test scores and subsequent declared college major.

These students have now also just completed the same college-level calculus class and received a grade. We are therefore now also interested to see if there is any relationship between the students' algebra test scores and their calculus course grades: On average, did students who tended to score higher on the high-school algebra test also finish the course with higher grades? Conveniently, only one student of each major received the same grade (see table - for example, there is only one Education major who received a grad of A).

Use the Microsoft Excel "Anova Single-Factor" Data Analysis tool to conduct a 2-way ANOVA test for the data in the following table:

Declared College Major
Grade	Education	Business/Management	Behavioral/Social Science	Fine Arts
A	62	89	68	87
A-	81	88	71	57
B+	75	82	52	62
B	58	69	50	64
B-	67	59	22	28
C+	48	73	31	29
C	16	40	42	30
C-	26	45	16	15

A high school physics teacher wondered if his students in the senior class this year will be more likely to go into STEM (Science, Technology, Engineering, Mathematics) majors than Social Science and Liberal Arts majors. He asked each of his 65 students about their first choice for major on their college applications and conducted a Chi-square test for goodness of fit with an alpha level of .05 to see if the number of students choosing each category differs significantly. 35...

About 130,000 high school students took the AP Statistics exam in 2010. The free-response section of the exam consisted of five open-ended problems and an investigative task. Each free-response question is scored on a 0 to 4 scale (with 4 being the best). For one of the problems, a random sample of 30 student papers yielded the scores that are graphed in the dot plot of part (a) in the previous problem. The mean score for this sample is x̄...

11. High School Standardized Test Past experience indicates that the time required for high school seniors to complete a standardized test is a normal random variable with a mean of 35 minutes (normally distributed). If a random sample of 30 high school seniors took an average of 33.5 minutes to complete this test with a standard deviation of 4 minutes, test the hypothesis, at the 0.05 level of significance, that u = 35 minutes against the alternative that u <35...

She knows that her first year tuition will be $14,000, due at the beginning of the year (that is, right away). Based on historical trends she estimates that tuition will rise at...
