A sample of 124 kissing couples were observed, with 44 of them leaning their heads to the left. Use these sample data to test whether or not the population proportion of kissing couples who lean their heads to the left is less than half. a. Report the test statistic: Z = _____ Round your final answer to two decimal places. Use either an exact p-hat or round to at least 3 decimal places. b. The p-value = ____ c Repeat part a, instead testing the theory that the proportion of people who lean to the left differs from 1/3. 1. Report the test statistic: Z = _____ Round your final answer to two decimal places. Use either an exact p-hat or pi round to at least 3 decimal places. 2. THE P- VALUE = ________ (ROUND TO 2 DECIMAL PLACES)
