- 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, 68 dream in black and white, and among 295 people under the age of 25, 15 dream in black and white. Use a 0.05 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. identify the test statistic? identify the p value ? 98% confidenc interaval? reject or not to reject and why?arrow_forwardIn the US, 46.2% of all people have type O blood, 39.1% have type A blood, 10.4% have type B blood and 4.3% have type AB blood.

- Determine if the survey question is biased. If the question is biased, suggest a better wording. How often do you eat vegetables during an average month? Is the question biased? OA. Yes, because it does not lead the respondent to any particular answer. A better question would be "Why is eating vegetables good for you?" OB. Yes, because it influences the respondent into thinking that eating vegetables is good for you. A better question would be "Do you think that eating vegetables is good for you?" OC. No, because it influences the respondent into thinking that eating vegetables is good for you. OD. No, because it does not lead the respondent to any particular answer.arrow_forward28arrow_forwardPortland State University (PSU) reported that 64% of their students receive financial aid.
