8.3 Inference for Quantitative Variable: Comparing Two MeansPulse Rates Mr. Wilcox's class performed an experiment to investigate whether drinking acaffeinated beverage would increase pulse rates. Twenty students in the class volunteeredto take part in the experiment. All of the students measured their initial pulse rates (inbeats per minute). Then Mr. Wilcox randomly assigned the students into two groups of 10.Each student in the first group drank 12 ounces of cola with caffeine. Each student in thesecond group drank 12 ounces of caffeine-free cola. All students then measured theirpulse rates again. The table displays the change in pulse rate for the students in bothgroups. Construct and interpret a 95% confidence interval for the difference in true meanchange in pulse rate for subjects like these who drink caffeine versus who drink nocaffeine.Change in pulse rate (Final pulse rate - Initial pulse rate)56 1441 2-1Caffeine8No caffeine 33-21-1STATE the parameter and confidence.level.DO all necessary visuals andcalculations.450504Two-sample t-interval for a difference between two meansMean change3.22.0PLAN the inference method and checkconditions.CONCLUDE with an interpretation of theconfidence interval in context.

Have you ever been frustrated because you could not get a container of some sort to release the last bit of its contents? An article reported on an investigation of this issue for various consumer products. Suppose five 6.0 oz tubes of toothpaste of a particular brand are randomly selected and squeezed until no more toothpaste will come out. Then each tube is cut open and the amount remaining is weighed, resulting in the following data: 0.51, 0.63, 0.42, 0.5, 0.35. Does it appear that the true average amount left is less than 10% of the advertised net contents? USE SALT (a) Check the validity of any assumptions necessary for testing the appropriate hypotheses.

Bighorn sheep are beautiful wild animals found throughout the western United States. Let x be the age of a bighorn sheep (in years), and let y be the mortality rate (percent that die) for this age group. For example, x = 1, y = 14 means that 14% of the bighorn sheep between 1 and 2 years old died. A random sample of Arizona bighorn sheep gave the following information: x 1 2 3 4 5 y 13.8 19.3 14.4 19.6 20.0 Σx = 15; Σy = 87.1; Σx2 = 55; Σy2 = 1554.45; Σxy = 274b) Find the equation of the least-squares line.

A consumer group wanted to determine if there was a difference in customer perceptions about prices for a specific type of toy depending on where the toy was purchased. In the local area there are three main retailers: W-Mart, Tag, and URToy. For each retailer, the consumer group randomly selected 5 customers, and asked them to rate how expensive they thought the toy was on a 1-to-10 scale (1= not expensive, to 10 = very expensive). The toy was priced the same at all retail stores. 1. What kind of statistical test should be used to test the consumer group's research goal, assuming that the researcher wanted to use the 1-to-10 scale as a numerical interval measure? A. Repeated-measures t-test B. One-way Independent Measures ANOVA C. Repeated-measures ANOVA D. Independent-measures t-test 2. State the hypothesis that aims to test the consumer group’s research goal (i.e., what is H0 and HA).
