A sample of n = 200 college students is asked if they believe in extraterrestrial life and 120 of these students say that they do. The data is used to test HO: p = 0.5 versus Hai p> 05., where p is the population proportion of college students who say they believe in extraterrestrial life. A p-value of 0.002 was obtained from Statkey. Suppose that the alternative hypothesis had been Ha: p * 0.5. What would have been the p-value of the test? p-value If we do not have an alpha (level of signi ficance) what do we assume it to be? alpha = in percent, alpha = in decimal format
