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.

In a science fair project, Emily conducted an experiment in which she tested professional touch Ktherapists to see if they could sense her energy field. She flipped a coin to select either her right hand or her left hand, and then she asked the therapists to identify the selected hand by placing their hand just under Emily's hand without seeing it and without touching it. Among 357 trials, the touch therapists were correct 169 times. Complete parts (a) through (d). S View an example Get more help. 4- & 87 U 0.5 (Type an integer or a decimal. Do not round.) b. Using Emily's sample results, what is the best point estimate of the therapists' success rate? 0.473 (Round to three decimal places as needed.) c. Using Emily's sample results, construct a 90% confidence interval estimate of the proportion of correct responses made by touch therapists. F

Oxygen consumption was measured in twelve individuals while they sat with their eyes closed listening to an exciting adventure story read by Taylor Swift or a restful instrumental medley performed by Metallica. Based on the results shown, is oxygen consumption less when listening to the music? Story Music 6.1 5.4 7.2 6.7 5.7 5.4 6.4 4.2 5.8 4.0 6.2 4.1
The following data lists the ages of a random selection of actresses when they won an award in the category of Best Actress, along with the ages of actors when they won in the category of Best Actor. The ages are matched according to the year that the awards were presented. Complete parts (a) and (b) below. Actress (years) 26 Actor (years) 26 32 28 38 29 29 45 27 31 D 60 37 40 40 28 36 50 35 41 43 a. Use the sample data with a 0.01 significance level to test the claim that for the population of ages of Best Actresses and Best Actors, the differences have a mean less than 0 (indicating that the Best Actresses are generally younger than Best Actors). In this example, Hd is the mean value of the differences d for the population of all pairs of data, where each individual difference d is defined as the actress's age minus the actor's age. What are the null and alternative hypotheses for the hypothesis test? Ho: Ha year(s) year(s) (Type integers or decimals. Do not round.)
In a computer game, different units are created randomly with different levels of range and Aggression according to the table below.

Blood pressure: A blood pressure measurement consists of two numbers: the systolic pressure, which is the maximum pressure taken when the heart is contracting, and the diastolic pressure, which is the minimum pressure taken at the beginning of the heartbeat. Blood pressures were measured, in millimeters of mercury, for a sample of 8 adults. The following table presents the results.
