Answer:
n = -2/5
Step-by-step explanation:
n/8 - 7n/16 = 1/8
2n/16 - 7n/16 = 2/16 (making common denominators)
-5n/16 = 2/16 (Simplifying the equation)
-5n = 32/16 (Multiplying both sides by 16)
-5n = 2
n = -2/5

Answer:
CAD = 128
Step-by-step explanation:
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.
