Answer:
You spilt up the shapes into triangles, rectangles, squares, etc
The equation for rectangles and squares is
A=l•w
(Area equals length times width)
The equation for triangles is
A=(1/2)b•h
(Area equals one half times bass times height)
Answer:
Step-by-step explanation:
n = 400
Proportion p = 229/400= 0.5725
For 95% confidence interval we use Z value as 1.96
Std error = 0.025
margin of error = 1.96*0.025
Confidence interval 95% = 0.5725±Margin of error
= (0.524, 0.621)
b) When smiled x becomes 277
p = 0.6925
Std error = 0.023
Margin of error= 1.96*0.023
Confidence interval = (0.647, 0.738)
Smiling increases the chances of stopping since mean and conidence interval bounds are showing increasing trend.
