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:
heart rate during exercise become 126 bpm
Step-by-step explanation:
maximum benefit is when heart beat increased by 50%-85%
alice resting heart rate= 70 bpm
increased heart rate of alice = 80%
increased heart rate =
total heart rate = 70+56=126 bpm
so, the heart rate of alice during exercise become 126 bpm
The measure of 1 would be 51
