Answer:
(a) A 90% confidence interval for the mean annual percent rate of change in childhood asthma hospital admissions in Scotland before the smoke-free legislation is between 4.5% and 5.9%
(b) A 90% confidence interval for the mean annual percent rate of change in childhood asthma hospital admissions in Scotland after the smoke-free legislation is between 16.41% and 19.99%
Step-by-step explanation:
Confidence Interval = mean% + or - standard error%
Before the smoke-free legislation, CI=5.2%+0.7%=5.9%
CI=5.2%-0.7%=4.5%
CI is between 4.5% and 5.9%
After the smoke-free legislation
CI=18.2%+1.79%=19.99%
CI=18.2%-1.79%=16.41%
CI is between 16.41% and 19.99%
F(x)=10x-7
f(0)=10(0)-7
f(0)=(0)-7
f(0)=-7
All triangle add up to 180
so 180-(96+48)
which is 36
so 36 is the missing interior angle
now all lines also equal 180
so 180-36=x
x=144
