A math teacher wants to determine if a new book proposed for the course will yield different results than the old book that was used before. The math teacher decided that 2 classes have different math ability coming into the course. He gives a test at the beginning of the semester to measure the math ability the students have when they come into the course. He uses the test to see if there is a difference between the 2 books. Old Book: 97, 94, 94, 95, 90, 91, 90, 85, 87, 92, 85, 81, 89, 83, 85, 80

New Book: 96, 95, 94, 92, 92, 90, 90, 89, 88, 88, 86, 86, 84, 84, 84, 83

Perform a significance test at the 1% level to see if the scores show a difference in the student's math ability.

huh? im pretty sure it is in 199

step-by-step explanation:

25 questions , because they start with 100.  

350-100=250 .  

. 250/10=25

step-by-step explanation:

first take off 100, then what x 10 = 250? that is your answer. (25)

in 2010, the population of the state of california is 37.29 × 10⁶

step-by-step explanation:

population of los angeles = 3.79 × 10⁶

population of california = 9.84 × population of los angeles

                                        = 9.84 × 3.79 × 10⁶

                                        = 37.2936 × 10⁶

                                        = 37.29 × 10⁶

∴ in 2010, the population of the state of california is 37.29 × 10⁶
