Let sample in Texas be p1, Louisiana be p2.
Null Hypothesis:
p1 - p2 = 0
Alternative Hypothesis: (This represents the claim)
p1- p2 < 0
To calculate test statistic, you need the pooled estimate which is a weighted average of the 2 sample proportions.
Next get standard error:
Calculate test statistic:
To find p-value, look up Z-value in standard normal table.
Anything smaller than -3 or larger than 3, you can estimate to have
p-value = 0.
If p-value < alpha, Reject Null Hypothesis.
For this example, 0 < 0.05, therefore reject null hypothesis.
There is evidence to support claim that proportion of smokers in Texas is LESS than Louisiana.

14.6 percent if it was percentage you ment by cent
Answer:
134.2258
Step-by-step explanation:
The side in front of 41 degree can be found using Sine formula, 19/sin(60)=x/sin(41), x=14.4. Next the missing angle is 79 degrees. The area of triangle in this case is (14.4*19)*sin(79)/2=134.2258
Your equation would be y = -2x + 3
-2 represents the constant, or slope, and +3 represents what y equals when x is zero
Hope this helps!
