Hello, I need help with sign tests and finding the test statistic and p values.

A study was conducted to determine the proportion of people who dream in black and white instead of color. Among 309 people over the age of​ 55, 68 dream in black and​ white, and among 295 people under the age of​ 25, 15 dream in black and white.
