Question
Transcribed Image Text:A health foods shop owner is wondering if his customers' daily vitamin supplement habits are in the same
proportion as the general population of adults. The shop owner heard in a news report that 60% of all adults
reported that they took a daily vitamin. The shop owner believes that his customers have a greater proportion
of adults who take a daily vitamin, so he decides to conduct a hypothesis test using the following null and
alternative hypotheses: Ho: p
selected customers and recorded that 45 of them use daily vitamin supplements.
= 0.6 and Ha: p > 0.6. The shop owner collected data from 50 randomly
(a) Compute the appropriate test statistic and find the p-value of the test and based on a 5% significance level.
Write a conclusion about the null hypothesis by interpreting the p-value. Be sure to clearly state the decision
regarding the null hypothesis.

- A newsletter publisher believes that over 33% of their readers own a Rolls Royce. For marketing purposes, a potential advertiser wants to confirm this claim. After performing a test at the 0.10 level of significance, the advertiser failed to reject the null hypothesis. What is the conclusion regarding the publisher's claim? Answer There is sufficient evidence at the 0.10 level of significance that the percentage is over 33%. There is not sufficient evidence at the 0.10 level of significance to say that the percentage is over 33%arrow_forwardRead through this scenario and look at the data that was collected. State the null and all possible research hypotheses. Review the results below (I used SPSS) and answer the questions that follow. Scenario: A researcher wants to see if gender and / or income affects the total amount of help given to a stranger who is sitting on the side of a busy road with a sign asking for help. The independent variables are gender, income, and the interaction of gender and income. The dependent variable is total help. He wants to know if one or both factors – or the interaction of the two - affects the total amount of help offered. Because he is analyzing two independent variables (gender and income), he used a factorial ANOVA. His results show the main effect of each of the independent variables on the dependent variable (total help) and the interaction effect. The researcher is using a 95% confidence interval which means that he wants to be at least 95% sure that his independent variables…arrow_forwardA study was done using a treatment group and a placebo group.
