Answer:
b. There is no difference between p1 and p2.
Step-by-step explanation:
Given that a 90% confidence interval for the difference of proportions contains some positive and some negative values
i.e. confidence interval lower bound is negative and upper bound is positive
This confirms that 0 is contained in the confidence interval for difference of proporitons at 90%
Hence for the hypotheses
we find that 0 is inside the confidence interval
This implies null hypothesis is accepted
Hence we conclude that there is no difference
b. There is no difference between p1 and p2.
Answer: 8400 $

Answer:
6
Step-by-step explanation:
You can do this algebraically:
Step 1: Write the unknown number as x
<em>The directions say subtract four from the number, and is equal to 2, so</em>
x - 4 = 2
Step 2: Add four to both sides
x = 6
Answer: Answer: 2.1 %
Step-by-step explanation:
Decrease = initial price - final price
% decrease = [ (initial price - final price) / initial price ] *100
% decrease =[ (2.89 - 2.83) / 2.89] * 100 = 2.08, which can be rounded to 2.1
