A study is performed to try to find evidence that two people claiming to have the ability to transfer thoughts directly to each other's minds actually have this ability, called telepathy. The first person will turn over 40 playing cards, one at a time, so that the second person cannot see them. The second person will try to determine the color of each card, red or black, telepathically. Since there are only 2 card colors, a person who has no special mental powers should be able to correctly guess the color of the card half the time. Therefore, this study will show evidence of telepathy if the second person can state the color of the cards significantly greater than half the time. which of the following best describes the parameter of interest in this study?

What should be used as the alternative hypothesis for this study?

Suppose the second person correctly determines the card color 25 out of 40 times. What is the correct test statistic?​

Write the equation of a line that is perpendicular to the given line and that passes through the given point. –3x – 6y = 17; (6, 3) y = x – 9 y = 2x – 9 y = –2x – 9 y = x + 0 3. is the relationship shown by the data linear? if so, model the data with an equation. x y 1 5 5 10 9 15 13 20 the relationship is linear; y – 5 = (x – 1). the relationship is not linear. the relationship is linear; y – 5 = (x – 1). the relationship is linear; y – 1 = (x – 5). write an equation in point-slope form for the line through the given point with the given slope. (–10, –1); m = y + 10 = (x + 1) y – 1 = (x – 10) y – 1 = (x + 10) y + 1 = (x + 10) 5. write an equation for each translation of . 6.5 units up y + 6.5 = | x | y = | 6.5 x | y = | x | + 6.5 y = | x | – 6.5 6. write an equation for each translation of . 5.5 units right y = | x | + 5.5 y = | x – 5.5 | y = | x | – 5.5 y = | x + 5.5 | 7. which equation translates y = | x | by 8 units to the left? y = | x | – 8 y = | x | + 8 y = | x – 8| y = | x + 8|
