WHAT ARE YOU ANSWER CHOICES?
Answer:
Option D - Because the Z* was only a little bigger than the Zc, the test supports the null hypothesis and we conclude μ = 10
Step-by-step explanation:
In z-value problems, the normal practice is that If the calculated z-value is less than the critical z-value, we will reject the null hypothesis and accept the alternative hypothesis but if it's greater than the critical z-value, we will fail to reject the null hypothesis and say that the test was not statistically significant.
In this problem, the calculated z-value of -1.49 is greater than -1.645, so we will fail to reject the null hypothesis and say that the test was not statistically significant.
Thus, in this question, we fail to reject the null hypothesis because the calculated value of z was bigger the value of z_c.
Answer: -34
Step-by-step explanation:
4x-7=-28
-28-6=-34
The answer is 61, x+40+5x+14=180, so x equals 21. 5(21)+14 ends up equaling 119, so 180-119 equals 1
Answer:
The coordinates of H’ is (-1,-6)
Step-by-step explanation:
Here, we want go get clockwise rotation about the origin
mathematically, if we had this kind of rotation, it would be that
(x,y) will turn to (y,-x)
So we have it that (6,-1 becomes)
(-1,-6)
