For statictics of Out of 780 smokers, 376 have been divorced, Non-smokers: Out of 2855 non-smokers, 902 have been divorced, the 95% confidence interval for smokers and non-smokers is mathematically given as
- 95% confidence interval = (0.5352, 0.4462)
- 95% confidence interval = (0.3424, 0.2894)
- 53% increased risk of divorce for smokers.
<h3>What is the 95% confidence interval for smokers and non-smokers?</h3>
Generally, the equation for the Confidence interval is mathematically given as
p ± Z/2[p(1-p)]/n
Where
Z1/2=1-(0.05/2)
Z1/2=0.975
Read z table we have
Z score= 1.96
Hence
0.4907 ± 1.96 (0.4907)(1-0.4907)/485
0.4907±0.0445
Therefore
95% confidence interval = (0.5352, 0.4462)
b)
Z1/2 = 1- (0.05/2)
Z1/2 = 0.975
Z score= 1.96
0.3159 ± 1.96 (0.3159)(1-0.3159)/1184
0.3159±0.0265
Thereofore
95% confidence interval = (0.3424, 0.2894)
c)
In conclusion, The 95% confidence interval helps us read that 53% increased risk of divorce for smokers.

Answer:
<u>y = 6x + 11</u>
Step-by-step explanation:
The slope-intercept form ⇒ y = mx + c
Where m is the slope and c is y-intercept
So, we need to change point-slope form to slope-intercept form
The given equation: y - 5 = 6 (x+1)
∴ y - 5 = 6x + 6 add 5 to each side of the equation
∴ y = 6x + 6 + 5
∴ y = 6x + 11
So, the equation written in slope-intercept form is <u>y = 6x + 11</u>
Answer:
nope
Step-by-step explanation:
Answer:
1) -4<x<0 = (-4,0)
2) x>=0 = [0, infinity)
3) 0<x<4 = (0,4)
4) -4<x<=4 = (-4,4]
5) x<=0 = (-infinity,0]
Step-by-step explanation:
Basically, we need to link inequalities with their solutions.
1) -4<x<0: solution to this inequality are all numbers between -4 and 0, or mathematically written (-4,0).
2) x>=0: solution to this are all numbers between 0 (including 0) and positive infinity, or [0, infinity)
3) 0<x<4: all numbers between 0 and 4, or in interval notation (0,4)
4) -4<x<=4: all numbers between -4 and 4 (including 4) which in interval notation is (-4,4]
5) x<=0: all the values from negative infinity to 0 (including 0), which is (- infinity,0]
Note that whenever there is symbol <= or >= we also need to include that value, and for noting that we use square bracket.
