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.
The statement that is true about the dot plots is: Range for Week 1 equals range for Week 2.
<h3>What is the Range of a Data Set?</h3>
Range is simply the difference between the highest data point and the lowest data point in a data set.
Range for Week 1:
Range = 89 - 62
= 27
Range for Week 2:
Range = 89 - 62
= 27
The sentence of median and mean doesn't satisfy the situation.
Hence, Range for Week 1 equals range for Week 2.

Answer:
<h2>a</h2>
Step-by-step explanation:
(+)(+) = (+)
(-)(-) = (+)
(+)(-) = (-)(+) = (-)
8 + (-8) + a = 8 - 8 + a = a
+(-8) = -8
8 - 8 = 0
