Answer:
50% is not a possible population proportion who support candidate A.
Step-by-step explanation:
I will estimate 95% confidence interval to see if 50% a possible population proportion who support candidate A.
95% Confidence Interval can be calculated using
CI=p± where
- z is the corresponding statistic in 95% confidence level (1.96)
- p is the sample proportion who support candidate A (70% or 0.70)
- N is the sample size (250)
Then CI=0.70±≈ 0.70±0.06
That is 95% confidence interval is (64%, 76%). Since 50% is less than lower CI limit, 50% is not a possible population proportion who support candidate A.
Answer is : 2^(7/6) x^(5/3) y^(1/6)
