Answer:
The correct answer is:
d. Cocaine, the first topical anesthetic drug, was introduced in 1880.
Explanation:
It is certainly true that Cocaine was introduced in the medical field for its anesthetic use in 1880, nevertheless it was not the first topical anesthetic drug used by medicine. The first discovery about anesthetic purposes was in 1844 with the use of nitrous oxide. Later on, ether was introduced to the field of anesthetics in 1846, and finally specialists talked about chloroform in 1847 before the later use of cocaine as anesthesia in the medical spheres.
The correct answer is: No, because the lack of assignment of communities to different levels of country music listening means there is a possibility of lurking variables.
Causation can only be determined in this case if the researchers randomly assigned different amounts of country music to different communities. They did not do this, so the study design doesn’t rule out lurking variables.
Answer:
A) 2.02 standard deviations from 600 - a win
B) The last interval was a close call.
Explanation:
n = 2300
p = 0.47, q = 1-p = 0.53
μ = np = 1081
σ = √(npq) = 23.94
Z.025 = 1.96
B) Finding both confidence interval:
Confidence Interval = (μ-1.96(23.94)/√2300, μ+1.96(23.94)/√2300)
= (1081 - 0.978, 1081 + 0.978)
= (1080.022, 1081.978)
(1080-600)/23.94 = 2.02 standard deviations from 600 - a win
B)
AS above
n=450, p=.54, q=.46
μ=np=243, σ=√(npq)=10.6
confidence interval (243-1.96(10.6)/√450 , 243+1.96(10.6)/√450)
= 243-.98, 243+.98) = (242.0, 243.98)
(244-225)/10.6=1.8 standard deviations from win
