Is the table correct, please correct it
The variable for this question is Race. Question to be investigated: According to the United States Census Bureau, in 2019 approximately 13.4% of the U.S. population identified themselves as black. Is the proportion of black participants lower for your chosen IAT? Respond to each of the following: a. State your hypotheses in symbolic form and in words. (The population of interest and themeaning of the proportion p in terms of the variable Race should be clear in your answer.) b. StatCrunchuses a normalmodel to estimate the P-value probability. Are the normality conditionsmet? Slow your work. c. Use StatCrunch to conduct the hypothesis test (directions). Copy and paste the results (the StatCrunch output window) into the tex tbox. d. Give your P-value and interpret its meaning as a conditional probability. State a conclusion that answers the research question. Use a significance level of 5%. Your answer should include the P-value and refefence the population and the appropiate variable.

For each question, you can find a description of the indicated variable on this Gender-Career IAT variable descriptions page. Question 1 The variable for this question is Assoc-Gen-Fam. a. Please state the IAT data set you are working with. b. Use StatCrunch to find the 95% confidence interval that estimates the population proportion of Gender-Career IAT participants who indicate that they associate neither males nor females with family (directions). Highlight and copy everything in your StatCrunch output window and paste it into your response. c. Identify the sample proportion (p^) in your StatCrunch output table. Then determine whether conditions are met for using the confidence interval to estimate the population proportion of participants in your chosen IAT. (Be sure to support your answer as demonstrated in Units 6 and 7 .) d. If conditions are met, estimate the population proportion of participants in your particular IAT, and state your conclusion in context. If conditions are not met, explain what a researcher could do so that conditions are met. e. Based on your analysis, do you think the population of participants in your chosen IAT is representative of the U.S. population? Explain. Question 2 The variable for this question is Race.
