He gathers data in order to test the hypotheses Ho: p = 0.38 vs. Ha: p > 0.38. In these hypotheses, what does p represent? A. The p-value B. The sample proportion C. The population proportion D. The sample mean E. The population mean 2....

6. A claim is made that college students spend 75% of their time on either sleeping or socializing. You do not believe this claim, and you set out to conduct a hypothesis test with the following hypotheses: Ho: p = 0.75 vs. Ha: p ≠ 0.75. If you gather data from a sample and compute a test statistic equal to -0.6, what would the p-value be? 7. Return to Question 6. The fact that the test statistic is negative tells...

se Information Ework In a previous year, 57% of females aged 15 and older lived alone. A sociologist tests whether this percentage is different today by conducting a random sample of 650 females aged 15 and older and finds that 302 are living alone. Is there sufficient evidence at the a=0.05 level of significance to conclude the proportion has changed? Because np. (1-P) - 150.310, the sample size is less than 5% of the population size, and the sample is...
