A large ice cream distributor wants to analyze the effect of season (winter, spring, summer, fall) on daily ice cream sales in dollars. How many independent variables does the manufacturer need to include in the multiple regression model?

4

Step-by-step explanation:

The independent variable is the variable used to explain the dependent variable.

The researcher wants to know how the seasons (independent variable) affects ice cream sales (dependent variable).

The researcher would regress ice cream sales against each season. There are four seasons, so the independent variable would be four

the above table 1 will calculate the population size (n) after a certain length of time (t). all you need to do is plug in the initial population number (no), the growth rate (r) and the length of time (t). the constant (e) is already entered into the equation. it stands for the base of the natural logarithms (approximately 2.71828). growth rate (r) and time (t) must be expressed in the same unit of time, such as years, days, hours or minutes. for humans, population growth rate is based on one year. if a population of people grew from 1000 to 1040 in one year, then the percent increase or annual growth rate is 40/1000 x 100 = 4 percent.
