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
Answer:
C
Step-by-step explanation:
There has to be two variables it's being compared to, in which case this is the blood sugar level and the amount of sugar
9q-4=3r-6
+4=+4
9r=3r-2
9/9=3r-2/9
r=3r-2/9
I’m sorry I can’t read that it’s too small..
