Answer:
D
Step-by-step explanation:
The margin of error represents the amount of percentage points that the real value can differ from the value given in the sample. The margin of error is ±3%, meaning that 50.6 (the sample value) ± 3% is the margin of error, resulting in a range of (47.6, 53.6) as our margin of error. Anything in that range can be the true proportion of voters that would vote for the ballot measure. As the range contains value both less than and greater than the 50% needed to pass, it is impossible to say, given the data, that the voters will vote yes or no to the ballot.
I got C. 92.08
I'm not 100% sure I did this right, but I took the money gained between years nine and eleven and divided it by 2. I tried a few other ways, but none of my answers were choices.
If the relationship between two quantities is a proportional relationship, this relationship can be represented by the graph of a straight line through the origin with a slope equal to the unit rate.
Answer:
a.H0: μ =530mL vs. Ha: μ > 530mL
Step-by-step explanation:
-A hypothesis test will be used to provide evidence that the median is more or equal to the stated median value.
#In a normally distributed population, the mean=mode=median:
-The null hypothesis states that the median is equal to the stated value:
-The alternative hypothesis provides evidence that the median value is greater than the stated value:
Hence, the correct hypotheses are H0: μ =530mL vs. Ha: μ > 530mL
