A public opinion poll surveyed a simple random sample of voters. Respondents were classified by gender (female or male) and by voting preference (Republican, Democrat, or Independent). The results are presented here: Republican 250 200 Female Male You want to determine if gender and voting preference are independent. Use a level of significance of a = 0.05. Are the requirements met for this hypothesis test? Explain. O Yes. A random sample was used, and all expected counts are greater than or equal to 5. O Yes. A random sample was used, and all observed counts are greater than or equal to 5. O No. A random sample was used, but at least one of the expected counts is less than 5. O No. A random sample was not used. Democrat 300 150 Independent 50 50

Suppose you are asked to conduct a two-tailed hypothesis test on the population mean. What type of hypothesis test would you use? Why? What assumptions do you need to make about the process when you are conducting a hypothesis test on the population mean in order for your results to be valid?
What does the p-value represent in a test of hypothesis? The p-value represents the significance level of the hypothesis test. The p-value is the probability that the sample data occurred given that the null hypothesis is true. The p-value is the probability that the sample data occurred given that the alternative hypothesis is true. The p-value is the probability that the null hypothesis is true.

use a hypothesis test to determine if the proportions are statistically different. A recent survey showed that in a sample of 100 elementary school teachers, 15 were single. In a sample of 180high school teachers, 36 were single. Is the proportion of high school teachers who were single greater than theproportion of elementary teachers who were single? Use ΅ = 0.01.

Hypothesis Testing: Means and Proportions According to a 2017 survey, 80% of Americans used at least one type of social media regularly in 2017. Rodrigo wants to know if this percentage has decreased since then, so he collects some data. He randomly samples 200 people and finds that 154 of them still use at least one type of social media currently. Test the claim that less than 80% of Americans currently use at least one type of social media regularly. Use the 0.05 significance level.
University X installed a new water fountain in the gym. The machine is designed to dispense 250 ml of water in a medium sze setting The staff suspects that the machine may be dispensing too much in medium bottles. They decided to take a sample of 50 medium bottles to see if the average amount is significantly greater than 250 ml What are appropriate hypotheses for their significance test? Select one O a HO p 250 ml. Ha p- 250 ml. (Where p is proportion of water dispensed on the setting) O b. HO 250 ml Ha. us 250 ml. (Where u is the average water dispensed on this setting) O C HO u 250 ml Ha 250 mi. (Where u is the average water dispensed on the setting) O d HO p 250 ml Ha pe 250 mt. (Where pis the proportion of water dispensed on this setting)
