(05.01 MC) Mateo is cooking beef. He must make sure the beef has a minimum internal temperature of 160 degrees so that it is safe to eat. Using a thermometer, he takes the temperature of the beef in five random places. The minimum temperature in the sample is 165 degrees. Identify the population and the sample. (4 points)

(06.03 MC) Aaliyah wants to determine how age and gender are related to movie genre preference in her town. She selects a simple random sample of 35 males from the 20- to 30-year age group and records their age, gender, and movie genre preference (comedy, romance, or horror). She also selects an independent simple random sample of 45 females from the 45- to 55-year age group and records the same information. Which is the most important observation about Aaliyah’s plan?

(06.06 LC) A scientist is interested in the relationship between the number of eggs hatched per day for frogs (y) and temperature. Based on the collected data, the least-squares regression line is ŷ = 15.66 + 3.58x, where x is the number of degrees by which temperature exceeds 60 degrees Fahrenheit. Which of the following statements best describes the meaning of the slope of the least-squares regression line? (3 points)
