Are American men or women more into online dating? Researchers from a pop culture magazine conducted a study to see if there is a difference in the proportion of men and women under 30 that use online dating sites. They collected independent random samples of 96 women and 88 men, ranging from 18-30 years old, from across the US. Of the women, 67 reported using online dating sites, while 62 of the men reported using online dating sites. Assume the subjects responded honestly. What would be the test statistic and P-value for performing a hypothesis test Ho : P1 = P2 vs. HA : P1 + P2 ? Select one: O a. z =-0.098 ; P-value = 0.9204 O b. z =-1.13 ; P-value = 0.1292 O c. z =-3.77 ; P-value is approximately 0 O d. z =-0.098 ; P-value = 0.4602 O e. z =-1.13 ; P-value = 0.2594 Clear my choice
A study was conducted to investigate the effectiveness of hypnotism in reducing pain.

Sample surveys on sensitive issues can give different results depending on how the question is asked. A University of Wisconsin study randomly divided 2400 respondents into three groups. All participants were asked if they had ever used cocaine. One group of 800 was interviewed by phone; 21% said they had used cocaine. Another 800 people were asked the question in a one-on-one personal interview; 25% said “Yes.” The remaining 800 were allowed to make an anonymous written response; 28% said “Yes.”101. Was this an experiment or an observational study? Justify your answer.2. Make a two-way table of responses about cocaine use by how the survey was administered.3. Are the differences between the three groups statistically significant? Give appropriate evidence to support your answer
A Deloitte employment survey asked a sample of human resource executives how their company planned to change its workforce over the next 12 months. A categorical response variable showed three options: the company plans to hire and add to the number of employees, the company plans no change in the number of employees, or the company plans to lay off and reduce the number of employees. Another categorical variable indicated if the company was private or public. Sample data for 180 companies are summarized as follows. Employment Plan Company Private Public Add Employees 37 32 No Change 19 34 Lay Off Employees 16 42 1) Conduct a test of independence to determine if the employment plan for the next 12 months is independent of the type of company. State the null and alternative hypotheses. A) H0: Employment plan is not mutually exclusive from the type of company. Ha: Employment plan is mutually exclusive from the type of company. B) H0: Employment plan is not independent of…

A real-estate appraiser wants to verify the market value for homes on the east side of the city that are very similar to size and style. The appraiser wants to test the popular belief that the average sales price is $37.80 per square foot for such homes. Suppose that a random sample of six sales were selected. The sampled sales prices per square foot are $35.00, $38.10, $37.20, $29.80, $30.30, and $35.40. Assuming a normal distribution is a good model for sales, test the claim that the mean sales price per square foot differs from $37.80 at the 1% significance level.
