Scores in the first and fourth (final) rounds for a sample of 20 golfers who competed in pga tournaments are shown in the following table (golfweek, february 14, 2009, and february 28, 2009). suppose you would like to determine if the mean score for the first round of a pga tour event is significantly different than the mean score for the fourth and final round. does the pressure of playing in the final round cause scores to go up? or does the increased player concentration cause scores to come down? a. use α = .10 to test for a statistically significantly difference between the population means for first- and fourth-round scores. what is the p-value? what is your conclusion? b. what is the point estimate of the difference between the two population means? for which round is the population mean score lower? c. what is the margin of error for a 90% confidence interval estimate for the difference between the population means? could this confidence interval have been used to test the hypothesis in part (a)? explain.

4+n=5

step-by-step explanation:

this is because the four is four hours and the n represents the 1 extra hour over the weekend.

b= i'm srry i don't know that one.

4+n=5 n=1 because if vernon plays 5 hours a week then 4+1=5 hours.

hope this : )

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.

78.59 is the mean

step-by-step explanation:

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
