In a recent sample of 250 households, 45% of them owned a video game console. A hypothesis test was performed using the following hypotheses: H_0: p = 0.40 \text{ vs. } H_a: p > 0.40H0:p=0.40 vs. Ha:p>0.40. A Type II error for this hypothesis test is: To conclude that 40% of households own a video game console when, in reality, it is more than 40%. To conclude that 40% of households own a video game console when, in reality, it is equal to 40%.
