A television executive postulates that 90% of households in the United States use social media as an alternative cable T.V. (this does not mean they do not watch T.V., it just means that social media is another option). The research team gathers a representative sample of households in the United States, conducts a hypothesis test of this claim, and they fail to reject the null hypothsis. If, in reality, 71% of households use social media as an alternative to cable T.V., was an error made? If so, what type?

	a.	Type II error
	b.	Incorrect null hypothesis
	c.	None of these
	d.	Bias test statistic due to a non-random sample being gathered
	e.	Type I error
