- A survey indicates that you should always try to negotiate for a better deal when shopping or paying for services. In fact, based on this survey, 30% of the people under the age of 34 were more likely to "haggle," compared to only 10% of those aged 65 and older. Suppose that this survey included 90 people under the age of 34 and 60 people who are 65 or older. (a) What are the values of Punder 34 and P65 or older for the two groups in this survey? under 34 P65 or over USE SALT = (b) Find a 95% confidence interval for the difference in the proportion of people who are more likely to "haggle" in the "under 34" versus "65 and older" age groups. (Round your answer to three decimal places.) toWhich rule(s) of inference are used? Question 6 Samantha will bring brownies or chocolate chip cookies to the party. Samantha did not bring brownies, therefore she brought chocolate chip cookies.In a recent study, 50 males used a new weight-loss supplement, and 39 of them experienced weight loss a 100 females used the same supplement, and 66 of them experienced weight loss after two weeks. Fill in the blanks below to make the most reasonable statement possible. The new weight-loss supplement was more effective on (Choose one) ▼ in the study. That is because only % of them failed to lose weight after two weeks, whereas % of the (Choose one) failed to lose weight after two weeks.
- A recent survey of wheat growers focused on the characteristics of wheat farmers and their willingness to participate in agricultural research. One of the variables of interest in the survey was the age of the farmer. The following bar chart shows the responses of the farmers, classified by age-group, regarding their willingness to participate. Which of the following statements is supported by the bar chart? I am choosing betwwen a positive association between the age of the farmers and their willingness to participate and a negative association between the age of the farms and their willingness to participate. I think it is a negative association because if we are talking about willingness the that mean they would say yes to participation, which means that the slope would be negative, but I am unsure.Four different beverages are sold at a fast-food restaurant soft drinks, tea, coffee, and bottled water.

- A high school track coach wanted to test whether giving the students an energy drink could affect performance during the 100 meter race. The coach split the 26 boys into two equal sized groups, where Group 1 was given the energy drink and Group 2 was not. The 100 meter race times were recorded during practice and shown in the table below. What inference can be made about the results? Group 1 Group 2 12.2 13 12.5 12.3 13.3 12.8 12.9 13 13 13.8 12.1 13 13 13 13 13 12.1 13 13 13 12.1 13 12.8 13 13 12.6 Mean: 12.7 Mean: 13 Since the simulation shows ( many cases or free cases )? where a mean difference of ( solve for this answer ) or less occurred when the groups were re-randomized, it can be inferred that the mean difference observed in the study was ( very possibly or very unlikely ) ?due to the random assignment of participants into groups, so the results of the study are (…Describe the ultimatum game8.
