Step-by-step explanation:
Fun. I prefer Oxymetazoline.
For the control group we have a headache probability of
c = 368/1671 = .220
For the experimental group we have a headache probability of
e = 494/2013 = .245
The observed difference is
d = e - c = .025
The variance of the difference is
s² = c(1-c)/n₁ + e(1-e)/n₂
so the standard deviation is
We get a t statistic on the difference of
t = d/s = .025/.0139 = 1.79
We're interested in the one sided test, P(d > 0). We have enough dfs to assume normality. We look up in the standard normal table
P(z < 1.79) = .96327
so
p = P(z > 1.79) = 1 - .96327 = 0.037 = 3.7%
Answer: That's less that 10% so we have evidence to conclude that headaches are significantly greater in the experimental group.
Using the graph of the scenario, the edge of the kiosk is 20 feet far from the entrance.
<h3>How to determine the distance of the edge ?</h3>The y value is given as:
y = 24
From the graph of this question (see attachment), we have the following coordinate
(x,y) = (20,24)
This means that the edge of the kiosk is 20 feet far from the entrance.
