Answer: slope: 7, y-intercept: 45, equation: y=7x+45
Step-by-step explanation:
y=mx+b
3=-6m+b
-4=-7m+b
subtract 1 from 2
-7=-m
m=7
-4=-49+b
b=45
Answer:
0.952
Step-by-step explanation:
we know that
here standard error =std deviation÷(n)^1/2
=15/(25)^1/2 =15/5=3
Assuming that IQ scores are normally distributed
Now, probability of a Type II error
=P(X<110) = P(Z<(110-105)/3)=P(Z<1.67)
=0.952
the power of the test if the true population mean is 105 = 0.952
The line is an upside U shape from A to B
This means the graph increases, then decreases.
Answer:
B;3
Step-by-step explanation:
That is because to complete the box you need the sum to subtract from one of the addends to be able to find the other and
28.42-24.72=3.7
Hope this helps:)
