An independent-measures research study compares three treatment conditions using a sample of n = 5 in each treatment. For this s

slavikrds [6]

Answer: c. 10

Step-by-step explanation:

Given : An independent-measures research study compares three treatment conditions using a sample of n = 5 in each treatment.

For this study, the three sample means are, M1 = 1, M2 = 2, and M3 = 3.

Grand mean = $\overline{X}=\dfrac{M1+M2+M3}{3}$ [All sample have equal elements]

$=\dfrac{1+2+3}{3}=2$

For ANOVA,

$SS_{between}=n\sum(M_i-\overline{X})^2$ , where i= 1, 2 , 3

$SS_{between}=5((1-2)^2+(2-2)^2+((3-2)^2)$

$SS_{between}=5((-1)^2+(0)^2+((1)^2)= 5(1+1)=10$

Hence,the value would be obtained for $SS_{between}=10$ .

hence, the correct answer = c. 10

A ship leaves port and travels due west for 30 knots, then changes course to S 30° W and travels 50 more knots. Find the bearing

leva [86]

Answer:

232°

Step-by-step explanation:

There are a couple of ways to find the desired direction. Perhaps the most straightforward is to add up the coordinates of the travel vectors.

30∠270° +50∠210° = 30(cos(270°), sin(270°)) +50(cos(210°), sin(210°))

= (0, -30) +(-43.301, -25) = (-43.301, -55)

Then the angle from port is ...

arctan(-55/-43.301) ≈ 231.79° . . . . . . . 3rd quadrant angle

The bearing of the ship from port is about 232°.

<em>Comment on the problem statement</em>

The term "knot" is conventionally used to indicate a measure of speed (nautical mile per hour), not distance. It is derived from the use of a knotted rope to estimate speed. Knots on the rope were typically 47 ft 3 inches apart. As a measure of distance 30 knots is about 1417.5 feet.
