<span>The sine, cosine, and tangent of 60 deg. is the same as 120, 240, and 300. 30 deg, 45 deg, and 60 deg. can each be matched to other counter parts across the quadrants. The only ones that have their own sin, cos, and tan are 90, 180, 270, and 360. The pi over 4 is a radian and can be found using an equation=
π/4*180/π
The two πs will cancel out and you are left with
180/4 which will give you the degrees. You would do the same equation for the π/6. This can also be used in reverse and you can find the radian using the degrees. Just multiply the degrees by pi/180 and then find a common multiple to reduce the fraction/radian down. pi will stay in your answe</span>

Critical value for 90% Confidence interval : 
a) Confidence interval :


Hence, a 90% confidence interval for the proportion of Americans who decide to not go to college because they cannot a ord it : 
b) Margin of error : E=1.5%=0.015
Formula for sample size : 
For p =0.48 , we have

Hence, the required sample size to survey = 3002
