A random sample of 25 college males was obtained and each was asked to report their actual height and what they wished as their ideal height. A 95% confidence interval for $\mu$_d = average difference between their ideal and actual heights was 0.8"to 2.2". Based on this interval, which one of the null hypotheses below (versus a two-sided alternative) can be rejected? A) H₀: $\mu$_d = 0.5 B) H₀: $\mu$_d = 1.0 C) H₀: $\mu$_d = 1.5 D) H₀: $\mu$_d = 2.0
