Answer:
a) Statistic.
b) The population proportion is expected to be between 0.29 and 0.31 with a 94% degree of confidence.
Step-by-step explanation:
a) The proportion of 30% is a statistic, as it is a value that summarizes data only from the sample taken in the study from USA Today. Other samples may yield different proportions.
b) We can use the statistic to estimate a confidence interval for the parameter of the population.
The standard error for the proportion is calculated as:

The margin of error is 0.01. We can use this value to determine the level of confidence that represents.
The formula for the margin of error is:

This z-value, according to the the standard normal distribution, corresponds to a confidence interval of 94%.
The interval for this margin of error is:

Then, we can conclude that the population proportion is expected to be between 0.29 and 0.31 with a 94% degree of confidence.
Answer:The answer would be 3/12 and 5/12 Because 4×3 = 12
29 is an irrational number.
Answer:
Step-by-step explanation:
Given it's a regular poligon, we calculate its angles as follows :
- (6-2)*180/6 get rid of parenthesis
- 4*180/6 then multiply
- 720/6 now divide it
- 120 is the measure of one angle and since it's a regular poligon each angle has same measure
