Pew Research Center poll of 1051 randomly selected U. S. adults showed that 70% of the respondents believe in global warming. The sample results are n = 1051, and sample proportion is
0.70 Find the margin of error E that corresponds to a 95% confidence level.
O 0.27705
O 0.23183
O 0.027705
O 0.023183

C) 0.0227705

Step-by-step explanation:

p = 0.70, n= 1051

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b
