Fast reactions: In a study of reaction times, the time to respond to a visual stimulus (x) and the time to respond to an auditory stimulus (y) were recorded foreach of 7 subjects. Times were measured in thousandths of a second. The results are presented in the following table.Visual161176178188201203211AuditoryPart: 0 / 4Part 1 of 4159163201193Critical value(s):197Send data to Excel206The least-squares regression line y = b + b₁ x=51.2341 +0.7203x and Σ (x-x)² = 1895.4286 are known for this data.

A recent study evaluated how addicted teenagers become to nicotine once they start smoking. The response variable was the number of yes answers on a questionnaire called the Hooked on Nicotine Checklist (HONC). Of teenagers who had tried tobacco, the mean HONC score was 3.8 (s = 4.8) for the 143 females and 2.3 (s = 2.8) for the 171 males. Complete parts a through c below. ... (Round to four decimal places as needed.) What does the standard error indicate? A. The standard error describes the spread of the sampling distribution of x₁ - x2- OB. The standard error is the standard deviation of the sample for this study. OC. The standard error is the difference in standard deviations for the two populations. OD. The standard error is the standard deviation of the difference between x₁ - x₂- b. Find the test statistic and P-value for Ho: H₁ H₂ and Ha: H₁ H₂. Interpret, and explain what (if any) effect gender has on the mean HONC score. Use the significance level 0.05. The test statistic is…
Do colors affect mood? You are particularly interested to know which color gives people a sense of serenity and peacefulness. You conduct an experiment by making participants stay for 20 minutes inside a room painted with a particular color (e.g., Red, Orange, Yellow, Green, Blue). With the use of temperature-sensitive cameras, you record the average body temperature of each individual during their stay inside each room (i.e., lower body temperatures are associated with feelings of calmness and relaxation; higher body temperatures - stimulation, excitement). Results are presented on the table. Red Orange 39 Yellow Green Blue 43 38 33 31 39 43 39 35 34 41 44 42 34 32 42 35 39 37 32 45 40 39 36 35 41 39 38 33 34
A test is being designed to compare the wearing quality of two brands of tires, say brand A and brand B. Six automobiles will be selected and equipped with the new tires from both brands and driven under normal conditions for 1 month. A measurement will be taken to determine how much wear took place on a scale from 0 to 200. Below is a table of the paired data collected from the 6 cars in the test.

An educational psychologist is interested in whether using a child’s own name in a story affected attention span while reading. Six children were randomly assigned to read a story under ordinary conditions (using common and generic names). Five other children read versions of the same story, but with each child’s ownname substituted for one of the children in the story. The researcher measured the amount of time (in minutes) each child spent reading the story. The results are shown in the following table. Does including the child’s namemake any difference in attention span? Test the hypothesis at an alpha set to .05, following these steps: a) write the null and alternative hypotheses; b) determine the critical value(s); c) draw the comparison distribution with rejection region(s) shaded; d)use the correct formula to compute the test statistic; e) state the statistical decision; f) state a brief conclusion.
