The letter is c because you divide 40 by 5 = 8
N + (n+1) + (n+2) = -369
3n + 3 = -369
3n = -366
n = -122
so the three consecutive integers are : -124 ; -123 ; -122
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
