Problem 28Multiple Choice

A survey of $1800$ college students found that $38 percent sign$ said they prefer online classes over in-person classes. Test the claim, at the $0.01$ significance level, that fewer than half of college students prefer online classes.

Fail to reject the null hypothesis; there is not insufficient evidence to support the claim that fewer than half prefer online classes.

Reject the null hypothesis; there is strong evidence to support the claim that more than half of the students prefer online classes.

Reject the null hypothesis; there is strong evidence to support the claim that fewer than half of the students prefer online classes.

Fail to reject the null hypothesis; the sample proportion is not significantly different from $50 percent sign$ .
