Ok i know this is hard but once you get it you will be fine. -2 is the y value in the order of pair (0,-2). So in the equation y=5x-b plug -2 into y (so that would be -2=5x-b). Then 0 is the x value in the order of pairs so plug 0 into x. ( So -2=5×0-b. start by combining terms, so multiply 5 and 0 such is p. So you are left with -2=-b. I am not completly sure but I don't think you y value can be negative so just flip all the signs and you are left with 2=b!
Answer:
a) z = -1.645
b) z = 0.674
Step-by-step explanation:
We have to find the value of z of a standard normal variable Z that satisfies each of the following conditions.
a) 5% of the observations fall below z
Calculation the value from standard normal z table, we have,
b) 25% of the observations fall above z
Calculation the value from standard normal z table, we have,
Answer:
B
