In a survey regarding same-sex marriages, 13% of a sample of 1025 adults in Country A said that same-sex couples should not have any legal recognition. The corresponding percentage for a survey of 1912 people in Country B was 16 %. Does a greater percentage of people in Country B hold this view than people in Country A? Let p, be the proportion of people in Country A that say same-sex couples should not have any legal recognition. Let p₂ be the corresponding proportion for Country B. Determine the null and alternative hypotheses. Ho: P₁ HA: P₁ P₂ P₂

A study was conducted to determine the proportion of people who dream in black and white instead of color. Among 309 people over the age of 55, 77 dream in black and white, and among 309 people under the age of 25, 18 dream in black and white. Use a U.U5 signiticance level to test the claim that the proportion of people over 55 who dream in black and white is greater than the proportion for those under 25 Complete parts (a) through (c) below. Consider the first sample to be the sample of people over the age of 55 and the second sample to be the sample of people under the age of 25. What are the null and alternative hypotheses for the hypothesis test? Identify the test statistic. z= (Round to two decimal places as needed.) Identify the P-value. P-value= (Round to three decimal places as needed.) What is the conclusion based on the hypothesis test? The P-value is ______ the significance level of a = 0.05, so ______ black and white is ____ the proportion for those under 25. There is…

The manager of a theater that is open to residents of two towns, A and B, wants to know if the proportion of households from A that use the library is smaller  than the proportion of households from B. In order to test this, the  manager asks 45 households in A and 49 households in B whether anyone in their household had used the theater last summer. 23 of the households surveyed in A responded "yes", and 35 of the households in B responded "yes". Find the p-value that would be used to make a conclusion for this hypothesis test.

1a. A recent study (Ackerman, Griskevicius, and Li, 2011) examined expressions of commitment between two partners in a committed romantic relationship. One aspect of the study involved 40 heterosexual couples who were asked about which person was the first to say "I love you." ...the 40 responses were used to see whether the male was more likely to say "I love you" first. 1.c] Write a paragraph, as if to the skeptics and the researchers, describing what your simulation analysis reveals about whether the data provide strong evidence in support of the researchers' conjecture. If you side with the researchers - explain why ... If you side with the skeptics - explain what it would take to be convincing evidence ...
