A = πr² - ¹/₂bh
A = 3.14(5)² - ¹/₂(10)(4)
A = 3.14(25) - ¹/₂(40)
A = 78.5 - 20
A = 58.5 u²
Median is 19
IQR is 12
Range is 22

Answer:
search it up its there
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.
