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.
6 out of 6 is the same as 6 divided by 6, or as fraction 6/6.
If you have 10 apples and you divide them into 2 groups there will be 5 in each group. (10/5 = 2)
Similarly, If you have 6 apples and you divide them into 6 groups, there will be one in each group.
Answer:
- 627 miles north
- 747 miles east
Step-by-step explanation:
Bearing angles are measured east of north, so in (N, E) coordinates, the final position of the plane is ...
(1.5 h)(650 mi/h)(cos(50°), sin(50°)) = (975cos(50°), 975sin(50°)) mi
= (626.72, 746.89) mi
The plane will be 627 miles north and 747 miles east of its point of departure.
