A Survey was conducted of newlyweds in a country who have a spouse of a different race or ethnicity from their own. The survey included random samples of 1000 newlyweds in Ethnicity A and 1000 newlyweds in Ethnicity B. In the survey, 13% of respondents in Ethnicity A and 24% of respondents in Ethnicity B had a spouse of a different race or ethnicity from their own. At a=0.01, is there evidence to support the claim that the proportion of newlyweds in Ethnicity A who have a spouse of a different race or ethnicity from their own is less than the proportion of newlyweds in Ethnicity B that have a spouse of a different race or ethnicity from their own? Let p, represent the proportion of newlyweds in Ethnicity A who have a spouse of a different race or ethnicity from their own. Let p, represent the proportion of newlyweds in Ethnicity B that have a spouse of a different race or ethnicity from their own. State the null and alternative hypotheses. A. Ho: P12 P2 H: P P2 H: P SP2 Calculate the standardized test statistic. z= -6.34 (Round to two decimal places as needed.) Calculate the P-value. P=0 (Round to three decimal places as needed.) State the conclusion of the hypothesis test Since P a, V Họ. There evidence to support the claim that the proportion of newlyweds in who have a spouse of a different race or ethnicity from their own is less than the proportion of newlyweds in Y that have a spouse of a different race or ethnicity from their own.

A study was conducted to determine the proportion of people who dream in black and white instead of color. Among 294 people over the age of​ 55, 78 dream in black and​ white, and among 291 people under the age of​ 25, 10 dream in black and white. Use a 0.01 significance 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 indentify test statistic p value= the 90% confidence interval is

A study was conducted to determine the proportion of people who dream in black and white instead of color. Among 303 people over the age of 55, 79 dream in black and white, and among 300 people under the age of 25, 18 dream in black and white. Use a 0.01 significance 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. a. Test the claim using a hypothesis test. 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? O A. Ho: P₁ = P₂ H₁: P₁ P2 O D. Ho: P₁ #P₂ H₁: P₁ = P2 Identify the test statistic. z=0 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 significance level of a = 0.01, so…

Twenty different statistic students are randomly selected. For each of them,their body temperature (° F) is measured and their head circumference (in) ismeasured. Without doing any research or calculations, estimate the value of r. Forthis sample of paired data, what does r represent?
