A study was conducted to determine the proportion of people who dream in black and white instead of color. Among 307 people over the age of 55, 68 dream in black and white, and among 313 people under the age of 25, 12 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. Complete parts (a) through (c) below.

You wish to test the following claim (H) at a significance level of a = 0.05. Ho:μ = 89.6 H: 89.6, You believe the population is normally distributed and you know the standard deviation is 19.5. You obtain a sample mean of 96.5 for a sample of size 50. a) What is the test statistic for this sample? (Report answer accurate to three decimal places.) test statistic = b) What is the p-value for this sample? (Report answer accurate to four decimal places.) p-value = c) The p-value is... O less than (or equal to) a O greater than a d) This test statistic leads to a decision to... O reject the null O accept the null O fail to reject the null e) As such, the final conclusion is that... There is sufficient evidence to warrant rejection of the claim that the population mean is not equal to 89,6. There is not sufficient evidence to warrant rejection of the claim that the population mean is not equal to 89.6. O The sample data support the claim that the population mean is not equal to 89.6.
1. AMA wants to compare the cholesterol levels of non smokers and smokers. Smokers: 230, 263, 255, 230, 218, 237, 221, 221, 188, 292, 205, 216, 205, 261, 251 Non-smokers: 245, 244, 170, 155, 208, 238, 220, 227, 195, 225, 212, 212, 129, 208, 169 Compare the cholesterol of smokers and non-smokers.
Past studies have indicated that the percentage of smokers was estimated to be about 31%. Given the new smoking cessation programs that have been implemented, you now believe that the percentage of smokers has reduced. You randomly surveyed 2088 people and found that 589 smoke. Use a 0.05 significance level to test the claim that the percentage of smokers has reduced. a) Identify the null and alternative hypotheses? Но: ? На: ? b) What type of hypothesis test should you conduct (left-, right-, or two-tailed)? left-tailed right-tailed two-tailed c) Identify the appropriate significance level. d) Calculate your test statistic. (Round your final answer to two decimal places.) e) Calculate your p-value. (Round your final answer to four decimal places.) f) Do you reject the null hypothesis? O We reject the null hypothesis, since the p-value is less than the significance level. We reject the null hypothesis, since the p-value is not less than the significance level. We do not reject the null…
Claim: Most adults would erase all of their personal information online if they could. A software firm survey of 640 randomly selected adults showed that 99.3% of them would erase all of their personal information online if they could. Make a subjective estimate to decide whether the results are significantly low or significantly high, then state a conclusion about the original claim.
if a researcher concludes that cereal color has no effect on amount consumed but the researcher was wrong in this conclusion which of the following best represents his decision? correct decision, type 1 error, type 2 error, or type 3 error
I am to do a project for an inferential statistics class and I would like some basic guidance. I am to propose a research question. My proposed research question is "Does drinking stimulants such as coffee improve a student's grades?" My population will be the students at my school. I will use a test of association hypothesis test because I will need to find an association between drinking stimulant’s such as coffee and the grades of the students. So, I will divide the students that do drink coffee before school and those who don’t and determine if there is a sizeable difference in academic success between the two groups. My question is what type of graph do you think would be best served to visually display the data?
A study was conducted to determine the proportion of people who dream in black and white instead of color. Among 297 people over the age of 55, 75 dream in black and white, and among 310 people under the age of 25, 19 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. Complete parts (a) through (c) below. a. Identify the test statistic. z= 6.51 (Round to two decimal places as needed.) Identify the P-value. P-value = 3.770o (Round to three decimal places as needed.) What is the conclusion based on the hypothesis test? The P-value is greater than the significance level of a = 0.05, so fail to reject the null hypothesis. There is insufficient evidence to support the claim that the proportion of people over 55 who dream in black and white is greater than the proportion for those under 25. b. Test the claim by constructing an appropriate confidence…
According to the Pew Research Center, 14% of adults rate basketball as their favorite sport. Your boss believes the proportion may be lower among adults over age 65, and wants you to collect evidence to see if this is true. What are the null and alternative hypotheses?

Claim: Most adults would erase all of their personal information online if they could. A software firm survey of 600 randomly selected adults showed that 62% of them would erase all of their personal information online if they could. Find the value of the test statistic.
Data for a certain community show that 18% of the adult residents are German. Suppose 74 people are called for jury duty and only 12 of them are German. Does this apparent underrepresentation of Germans call into question the fairness of the jury selection system? Explain. Write appropriate hypotheses. H0: ▼ p not equals 18 %p≠18% p equals 18 %p=18% p greater than 18 %p>18% p less than 18 %p<18% HA: ▼ p equals 18 %p=18% p not equals 18 %p≠18% p greater than 18 %p>18% p less than 18 %p<18% The test statistic is z=_______________ (Round to two decimal places as needed.) The P-value is _____________________ (Round to three decimal places as needed.) State your conclusion assuming a P-value smaller than 0.05 is significant.
