Answer:
m∠ADC = 132°
Step-by-step explanation:
From the figure attached,
By applying sine rule in ΔABD,


sin(∠ADB) = 
= 0.74231
m∠ADB = 
= 47.92°
≈ 48°
m∠ADC + m∠ADB = 180° [Linear pair of angles]
m∠ADC + 48° = 180°
m∠ADC = 180° - 48°
m∠ADC = 132°
Answer:
Assumptions are not met. Can not make confidence interval.
Step-by-step explanation:
In the General Social Survey, sample size is 1514.
The proportion of those who see themselves social is
≈ 0.31
To give an 95% confidence interval, we should be able to calculate margin of error of the sample mean, which is given by the formula
M±
where M is the mean of the sample (in the General Social Survey it is 0.31), z is z-score for the 95% confidence level(approx. 1.94), s is the standard deviation of the sample, N is the size of the sample(in this example it is 1514).
Since we don't know the standard deviation of the sample, we cannot give a confidence interval.
