Answer and explanation:
Null hypothesis: p is not 54%
Alternative hypothesis : p is equal 54%
First find standard deviation
Standard deviation is:
σ = √[ P ( 1 - P ) / n ] = √[ 0.54×0.46/220 ] =0.033
The z score is calculated p-P/σ = (0.54-0.50)/0.033 = 1.2121
Therefore we can conclude that proportions are not same and fail to reject the null hypothesis
3000 + 70 + 2
It's basically everything that is added to get that number. You do not need a 100's place because a 0 is holding that spot.
The answered the question is X=5
The equation y = x^2 has axis of symmetry of x = 0
The answer to the question is y = x^2 + 2 which is y = x^2 moved vertically up to 2 units
