Question Help ▼ A student at a junior college conducted a survey of 20 randomly selected full-time students to determine the relation between the number of hours of video game playing each week, x, and grade-point average, y. She found that a linear relation exists between the two variables. The least-squares regression line that describes this relation is y= -0.0552x + 2.9446. (a) Predict the grade-point average of a student who plays video games 8 hours per week. The predicted grade-point average is. (Round to the nearest hundredth as needed.)

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
