Smokers: Out of 780 smokers, 376 have been divorced.
beks73 [17]

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.

Identify the intervals on which each quadratic function is positive Part 1
Gemiola [76]

Answer:  1) (-∞, -6) U (-3, ∞)

               2) (-∞, -4) U (2, ∞)

               3) (-∞, -3) U (8, ∞)

<u>Step-by-step explanation:</u>

Find the zeros. Since the a-value is positive, the curve will be positive to the left of the leftmost zero and to the right of the rightmost zero.  +   -   +

                                                                                                     ←---|----|--→

1) y = x² + 9x + 18

  y = (x + 3)(x + 6)

 0 = (x + 3)(x + 6)

 0 = x + 3       0 = x + 6             +         --           +

 x = -3             x = -6              ←------|-----------|--------→

                                                     -6           -3

Positive Interval: (-∞, -6) U (-3, ∞)    

2) y = x² + 2x - 8

  y = (x + 4)(x - 2)

 0 = (x + 4)(x - 2)

 0 = x + 4       0 = x - 2              +         --          +

 x = -4             x = 2               ←------|-----------|--------→

                                                     -4            2

Positive Interval: (-∞, -4) U (2, ∞)    

3) y = x² - 5x - 24

  y = (x + 3)(x - 8)

 0 =  (x + 3)(x - 8)

 0 = x + 3       0 = x - 8               +        --           +

 x = -3             x = 8               ←------|-----------|--------→

                                                     -3            8

Positive Interval: (-∞, -3) U (8, ∞)
