m_a_m_a [10]

Answer:

Step-by-step explanation:

Sum of all the angles of a triangle is 180

Let the third angle be 'x'

41 + 22 + x = 180

     63 + x = 180

             x = 180 - 63

Allisa [31]

Answer: 323

Step-by-step explanation:

The formula to calculate the sample size for proportion is given by :_

n=p(1-p)(\dfrac{z_{\alpha/2}}{E})^2

Given : Significance level : \alpha: 1-0.95=0.095

Critical value : z_{\alpha/2}=1.96

Margin of error : E=0.05

The proportion of successes : p=0.70

Now, the required sample size will be :-

n=0.70(0.30)(\dfrac{(1.96)}{0.05})^2=322.6944\approx323

Hence, the minimum required sample size = 323
