- In 1974, Loftus and Palmer conducted a classic study demonstrating how the language used to ask a question can influence eyewitness memory. In the study, college students watched a film of an automobile accident and then were asked questions about what they saw. One group was asked, "About how fast were the cars going when they smashed into each other?" Another group was asked the same question except the verb was changed to "hit" instead of "smashed into." The "smashed into" group reported significantly higher estimates of speed than the "hit" group. Suppose a researcher repeats this study with a sample of today's college students and obtains the following results. EstimatedSpeed Hit Smashed into n1 = 15 n2 = 15 x̅1 = 40.8 x̅2…Sales of RedShoes.com follow a peculiar, but predictable, pattern that determines how many units will sell in any given year.

- Claim: The mean systolic blood pressure of all healthy adults is less than 122 mm Hg. Sample data: For 269 healthy adults, the mean systolic blood pressure level is 121.74 mm Hg and the standard deviation is 15.02 mm Hg. Complete parts (a) and (b). a. Express the original claim in symbolic form. Let the parameter represent a value with respect to systolic blood pressure of a healthy adult.The 94 students in a statistics class are categorized by gender and by the year in school.

What would be the entry (in proportions) for male sophomores?Time can be expressed on different levels of scale, including days, weeks, months, and years. Can the scale provided influence perception of time? For example, if you placed an order over the phone, would it make a difference if you were told the package would arrive in four weeks or in one month? To investigate this, two researchers asked a group of 267 college students to imagine that their car needed major repairs and would have to stay at the shop. Depending on the group they were randomized to, the student was either told it would take 1 month or 30/31 days. Each student was then asked to give best- and worst-case estimates of when the car would be ready. The interval between these two estimates (in days) was the response. Here are the results: Group 30/31 days In 177 20.4 14.3 1 month 90 24.8 13.9 Suppose you want to construct a 95% confidence interval for the difference in populations means (30/31 days minus 1 month). What would be the upper limit of the 95% confidence interval?…
