Answer:
First point goes on -2
Step-by-step explanation:
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
He had 9.43 pounds of gummy bears
X+11=3
-11 -11
x=-8
you subtract 11 from both sides. then you got the answer.
