Please use the accompanying Excel data set or accompanying Text file data set when completing the following exercise. The overall distance traveled by a golf ball is tested by hitting the ball with Iron Byron, a mechanical golfer with a swing that is said to emulate the legendary champion, Byron Nelson. Ten randomly selected balls of two brands are tested and the overall distance measured. Assume that the variances are equal. The data follow: Brand 1: 279 282 287 271 283 271 279 275 263 267
Brand 2: 262 243 260 265 273 281 271 270 263 268
(a) Is there evidence to show that there is a difference in the mean overall distance of brands? Use a = 0.05.
(b) Calculate a 95% two-sided confidence interval on the difference in mean overall distance. Round your answer to one decimal place (e. g. 98.7).
≤ μ1 – μ2 ≤

the answer is somewhere there guys it really . there im just not gonna answer

step-by-step explanation:

but i'm guessing ur first option tho

omg what happend to your question? if you could edit this question i can

need more information

step-by-step explanation:

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.
