Step-by-step explanation:
Data given and notation
represent the average score for Rutgers College in 2000
represent the average score for Rutgers College in 2002
represent the sample standard deviation in 2000
represent the sample standard deviation in 2002
sample size
State the null and alternative hypotheses. .
What are H0 and Ha for this study?
Null hypothesis:
Alternative hypothesis :
For this case we need to take in count that the alternative hypothesis can't have and = sign, and based on the information a good hypothesis here would be if the average GPA increased between 2000 and 2002, so based on this the best option for this case would be:
C. The mean Rutgers College GPA has increased to more than 3.15

The formula for volume of a rectangular prism is L x W x H
we can replace the letters with the information given and then solve for the missing letter:
240 cm^3 = 12 x 4 x H
multiply 12 and 4:
240 = 48 x H
now to solve for H divide both sides by 48:
h = 240/48
H = 5
the height is 5 cm
