(3 points) Independent random samples, each containing 80 observations, were selected from two populations. The samples from pop

ulations 1 and 2 produced 57 and 46 successes, respectively. Test H0:p1=p2H0:p1=p2 against Ha:p1≠p2Ha:p1≠p2. Use α=0.02α=0.02.
(a) The test statistic is
(b) The P-value is
(c) The final conclusion is
A. We can reject the null hypothesis that (p1−p2)=0 and conclude that (p1−p2)≠0.

Sending 12 dollars Paypal to People who Only get this right (I MADE IT SO IM WATCHING TO SEE WHO GETS IT CORRECT) :D GOOD LUCK
11111nata11111 [884]

Answer:

Answer # 1 and answer #4

Step-by-step explanation:

If line XY is a bisector, it divided the line YW in half, therefore making ZY equal to ZW

Euclids 1st book proposition 13 states that a line standing on another line makes 2 right angles. therefore <YZW is a right angle because that angle plus <WZX must be equal to 180 and line YW splits the angles in half

2. A square-based tent has the cross-sectional
ollegr [7]

(a) Length of the height is 2.732 m

(b) Length of the base is 5.466 m

<u>Explanation:</u>

An image is attached for reference.

(a)

In ΔAOB,

sin 30^o = \frac{AO}{AB} \\\\0.5 = \frac{AO}{2} \\\\AO = 1 m

In ΔBGD,

sin 60^o = \frac{BG}{BD} \\\\0.866 = \frac{BG}{2} \\\\BG = 1.732 m

According to the figure, BG = OE = 1.732 m

Height of the tent, AE = AO + OE

                                  = 1 m + 1.732 m

                                  = 2.732 m

(b)

DF = ?

In ΔAOB,

tan 30^o = \frac{AO}{OB} \\\\0.577 = \frac{1}{OB} \\\\OB = 1.733 m\\\\\\

According to the figure, OB = GE = 1.733 m

In ΔBGD,

tan 60^o = \frac{BG}{DG} \\\\1.732 = \frac{1.732}{DG}\\ \\DG = 1m

According to the figure, DE = DG + GE

                                      DE = 1 m + 1.733 m

                                     DE = 2.733 m

Length of the base, DF = 2 X DE

                              DF = 2 X 2.733 m

                               DF = 5.466 m
