(0,2)and (3,-2)
slope = (2+2)/(0-3) = -4/3
y intercept b = 2
equation
y = -4/3 x + 2
Answer is A
y = -4/3 x + 2
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.
Answer:
Regular = $0.21 per ounce, Family = $0.19 per ounce
Step-by-step explanation:
Regular
16oz = $3.36
Divide by 16 on both sides
1oz = $0.21
Family
40oz = $7.20
divide by 40 both sides
1oz = $0.19
Answer:
(f - g)(x) = f(x) - g(g) = (3x + 1) - (x2 - 6) = -x^2 + 3x + 7
