Answer:
As the calculated value of z does not lie in the critical region the null hypothesis is accepted that the GPA mean of the night students is the same as the GPA mean of the day students.
Step-by-step explanation:
Here n= 20
Sample mean GPA = x`= 2.84
Standard mean GPA = u= 2.55
Standard deviation = s= 0.45.
Level of Significance.= ∝ = 0.01
The hypothesis are formulated as
H0: u1=u2 i.e the GPA of night students is same as the mean GPA of day students
against the claim
Ha: u1≠u2
i.e the GPA of night students is different from the mea GPA of day students
For two tailed test the critical value is z ≥ z∝/2= ± 2.58
The test statistic
Z= x`-u/s/√n
z= 2.84-2.55/0.45/√20
z= 0.1441
As the calculated value of z does not lie in the critical region the null hypothesis is accepted that the GPA mean of the night students is the same as the GPA mean of the day students.
Answer: 16 units
Step-by-step explanation:
Point A and Point B are 5 units apart on the x-axis.
Since this is a rectangle, the opposite side is equivalent.
Point A and Point C are 3 units apart on the y-axis.
Same thing applies for these points.
5+5+3+3=16 units
To combine like terms, check if there are any terms just like the first one, and we see 6xy. 9xy + 6xy = 15xy. So that is one term. Now I would see if the second term has any terms like the first one, and we see -3y. So -3y + (-3y), we would get -6y. That means our polynomial is now 15xy - 6y, and because this has two terms, it is a binomial. Hope this helps. Please rate, leave a thanks, and mark a brainliest answer. (Not necessarily mine). Thanks, it really helps!
I think what may be confusing is the fact that they also list two three digit numbers with two decimal places each. Since the number is greater than 4.49 with only two digits, it can't be 4.5 since the tenths place is odd. Same goes for less than 4.71. So the only answer would be 4.6--two digits, even tenths place, greater than 4.49 and less than 4.71.
Just some logical thinking, I guess. I think they were trying to trick you on this one.
Good luck.
