Answer:
Null hypothesis H0: µ = $1,338
Alternative hypothesis Ha: µ ≠ $1,338
Which means;
Null hypothesis H0; the average household expenditure for energy is equal to $1,338
Alternative hypothesis Ha; the average household expenditure for energy is not equal to $1,338
Step-by-step explanation:
The null hypothesis (H0) tries to show that no significant variation exists between variables or that a single variable is no different than its mean. While an alternative Hypothesis (Ha) attempt to prove that a new theory is true rather than the old one. That a variable is significantly different from the mean.
Therefore, for the case above;
Null hypothesis H0: µ = $1,338
Alternative hypothesis Ha: µ ≠ $1,338
Which means;
Null hypothesis H0; the average household expenditure for energy is equal to $1,338
Alternative hypothesis Ha; the average household expenditure for energy is not equal to $1,338
