Answer:
it decreases by 31.50 ur welcome
Step-by-step explanation:
Look in the file below for the answer
The slope is y=3x-7
a= y=3x-6 (or any number as long as the slope is same)
b = y=-1/3x -7
23+23+16+16=78
78 is the perimeter:)
Answer:
A. It is a two tailed test about a proportion
Step-by-step explanation:
We are given;
Population proportion; p= 8% = 0.08
Sample size; n = 450
Defective ones in the sample = 27
Sample proportion; p^ = 27/450 = 0.06
Let's define the hypotheses.
Null Hypothesis; H0: p = 0.08
Alternative hypothesis;Ha: p ≠ 0.08
≠ is used for the alternative hypothesis because we can't really ascertain if the training was going to make things worse.
Thus, this is a two tailed hypothesis test about a proportion.
