The pooled sample proportion was (234 + 117)/(283 + 163) = 0.79. Carry out a one-sided z test by hand to see if the proportion carrying cell phones was significantly higher for females. (Round your answer to two decimal places.) Z = The P-value would be considered which of the following? O equal to 0.005 O less than 0.005 more than 0.005 Do we conclude there is a significant difference between proportions carrying cell phones for males versus females? Yes NO Additional Materials eBook
