select

b. as the number of letters in a person’s name increases, the last digit of their phone number is predicted to
select

c. as the number of ice cubes in a drink increases, the temperature of a drink is predicted to
select

Explanation:

To solve these, we analyze the relationship between the variables:

Part (a)

As hours spent playing a video game (independent variable) increase, typically, the level reached (dependent variable) also increases (positive association, since more practice/playtime leads to higher levels). So the level is predicted to increase.

Part (b)

The number of letters in a name and the last digit of a phone number are unrelated (no logical association between name length and phone number digits). So the last digit is predicted to show no association (or be unpredictable) (since the two variables are independent).

Part (c)

As the number of ice cubes in a drink increases, the drink’s temperature decreases (ice cools the drink). So the temperature is predicted to decrease.

Answer:

s:
a. Increase
b. Show no association (or be unpredictable)
c. Decrease
