Given $\mathrm { H } _ { 0 } : \mathrm { p } \geq 0.45 \text {, }$ for which confidence interval should you reject $\mathrm { H } _ { 0 } ?$
A)(0.32, 0.40)
B)(0.40, 0.50)
C)(0.42, 0.47)

The confidence interval (0.32, 0.40) does not include the null hypothesis value of $p = 0.45$, indicating that the true proportion is likely less than 0.45, leading to rejection of $H_0$.

Given H0:p≥0.45, \mathrm { H } _ { 0 } : \mathrm { p } \geq 0.45 \text {, }H0​:p≥0.45,
