Answer:
Data is quantitative, data is categorical, data must be from a simple random sample, the data mut have normal distribution,
Step-by-step explanation:
When we make inference about one population proportion, we must ensure that the sample was taken randomly and observations follow a normal distribution. The sample size must be as large as possible with at least 10 counts of failures an 10 counts of successes. The individual observations must be independent. They must be quantified and categorized.

Answer: 68 degrees
Step-by-step explanation:
The sum of the angles in a triangle is 180 degrees.
Since we are given 2 of the angles, we can set up an equation.
Let the measure of angle G = g.
Then, g + 97 + 15 = 180
g + 112 = 180
g = 68
