Answer:
See below
Step-by-step explanation:
A 30° angle is measured 30° counterclockwise while a -30° angle is measured 30° clockwise. Therefore, you can say -30°=360-30°=330° because 30° is a reference angle located in Quadrant IV.

Answer:
There is 95% confidence that the true value of the population proportion is included in the interval (0.33, 0.45).
Step-by-step explanation:
The (1 - <em>α</em>)% confidence interval for population parameter implies that there is a (1 - <em>α</em>) probability that the true value of the parameter is included in the interval.
Or, the (1 - <em>α</em>)% confidence interval for the parameter implies that there is (1 - <em>α</em>)% confidence or certainty that the true parameter value is contained in the interval.
The 95% confidence interval for the population proportion is calculated to be 0.39 ± 0.06.
The interval is:
CI = (0.33, 0.45)
This confidence interval implies that, there is 0.95 probability that the true value of the population proportion is included in the interval (0.33, 0.45).
Or, there is 95% confidence that the true value of the population proportion is included in the interval (0.33, 0.45).
