Answer: INDEPENDENT SAMPLES T-TEST
Step-by-step explanation:
Given that;
sample size n₁ = 40, sample size n₂ = 40
sample mean x₁ = 32.9, sample mean x₂ = 30.6
Standard deviation S₁ = 4.4, Standard deviation S₂ = 5.1
Now
NULL hypothesis H₀ : u₁ = u₂
and Alternative hypothesis H₁ : u₁ > u₂
Therefore based on the information provided above, the type of test that should be used to determine whether the level of nicotine are now lower than what they were 10 years ago is the INDEPENDENT SAMPLES T-TEST
Answer:
A) 100%; B) 0.517; C) 0.858
Step-by-step explanation:
For part A,
We find the sum of the probabilities:
45.2+16.4+6.5+6.3+4.2+3.7+2.1+15.6 = 100
Since they sum to 100%, this is a probability distribution.
For part B,
We add together the probabilities for the US and Canada:
45.2+6.5 = 51.7% = 51.7/100 = 0.517
For part C,
We first add together the probabilities for Italy, the UK and France:
6.3+4.2+3.7 = 14.2%
Next we subtract this from 100%:
100-14.2 = 85.8% = 85.8/100 = 0.858
