Incidence rates of COPD (chronic obstructive pulmonary disease) from samples obtained from smokers and nonsmokers are given below. Occurrence of Asthma
Smoker m = 925 x = 222
Nonsmoker n = 1055 y = 211
Find a 95% confidence interval for the difference in COPD incidence rates between smokers and nonsmokers. Find the upper bound of the confidence interval (round off to first decimal place).

42%

step-by-step explanation:

we know,

total people = 60

total males = 25

percentage of males

= 25/60 × 100

= 25/6 × 10

= 25/3 × 5

= 125 / 3

= 41.

rounding of = 42%

pls mark as brainliest

is this part of a question or something

hi there!

first we need to find out how much they are adding to each number to make the next number.

ex: 4 + 4 = 8, 8 + 8 = 16, and so on.

so continuing with 32,

32 + 32 = 64

64 + 64 = 128

128 + 128 = 256

256 + 256 = 512

4, 8, 16, 32, 64, 128, 256, 512

the 8th term of the sequence will be 512
