At a certain university, the average attendance at basketball games in the previous year was 3000 spectators per game. for the first 14 games of the current year, there has been an average of 3200 spectators per game with a standard deviation of 450. the athletic director claims that the attendance this season is up from last year. using a significance level of ? = .05, is there evidence to support his claim? since the test statistic 1.66 is greater than the significance level, there is significant evidence that the director's claim is correct. since p = .0601, there is not enough evidence to support the director's claim. since p = .0482, there is significant evidence that the athletic director's claim is correct. since the sample mean is 3200, the athletic director is right. a.since the test statistic 1.66 is greater than the significance level, there issignificant evidence that the director's claim is correct. b.since p = .0601, there is not enough evidence to support the director's claim. c.since p = .0482, there is significant evidence that the athletic director's claim is correct. d.since the sample mean is 3200, the athletic director is right.

hope it is correct if not i'm srry i tried to

Answer: question no. 1 -a. yes, the sides are in the ratio 2 : 5.question no. 2 -b. 59°question no. 3 -c. angles x and y are remote interior angles.question no. 4 -d. 90°, 45° and 45°question no. 5 -b. mn and qrstep-by-step explanation: question no. 1 -rs : xu = 3 : 7.5 = 2 : 5rt : x? = 6.4 : 16 = 2 : 5st : u? = 6 : 15 = 2 : 5as the ratios of all sides are equivalent, the triangles must be congruent and the sides must be proportional.therefore, the answer is: a. yes, the sides are in the ratio 2 : 5.question no. 2 -in the second diagram, angle b is the only letter not shown. therefore, the number must be equivalent to angle b.if we substitute the value of angle b as being 22° in the first diagram, we can now use the angle sum of a triangle to obtain the value of angle a.angle sum of a triangle = 180°therefore: let angle a = aa + 99 + 22 = 180a = 180 - 99 - 22a = 59°therefore, the answer is: b. 59°question no. 3 -angles x and y don't share the vertex of the triangle with the exterior angle w. remote interior angles don't share a vertex of a triangle with an exterior angle. this means that angles x and y are remote interior angles.therefore, the answer is: c. angles x and y are remote interior angles.question no. 4 -the sum of all interior angles of a triangle must be equivalent to 180°.90°, 45° and 45° are the only set of angle measures that are equivalent to 180°.therefore, the answer is: d. 90°, 45° and 45°question no. 5 -the only pair of sides stated in the options which are corresponding are mn and qr.therefore, the answer is: b. mn and qr.
