Activity 3. Bowling League Directions: Read the situation and answer the following questions. Myla runs a large bowling league. She suspects that the league average score is greater than 150 per game. She takes a random sample of 36 game scores from the league data. The scores in the sample have a mean of 156 and a standard deviation of 30. Fernanda wants to use these sample data to conduct a test-statistic on the mean. Assume that all conditions for inference have been met. a. What is the sample mean (x)? b. What is the population mean (u)? c. What is the sample standard deviation (s)? d. What is the sample score (n)? е. Which of the two formulae will be used?

Ratios

A ratio is a comparison between two numbers of the same kind. It represents how many times one number contains another. It also represents how small or large one number is compared to the other.

Trigonometric Ratios

Trigonometric ratios give values of trigonometric functions. It always deals with triangles that have one angle measuring 90 degrees. These triangles are right-angled. We take the ratio of sides of these triangles.
