M = y2-y1/x2-x1
m = 7- (-2)/ -6-(-7)
m = 9/1
slope = 9
63.5 if u want working out let me know
Combine like terms Finding the next equation
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
