A forensic psychologist conducts a study examining whether being hypnotized during recall affects the number of facts a witness recounts. He separates his participants into two groups and have each view a short film of a mock robbery. The hypnotized sample of 14 witnesses recalled, on average, 17 facts with a sample variance of 47.3. The sample of 14 participants who were not hypnotized recalled, on average, 22 facts with a sample variance of 45.6. Given this scenario, first calculate and report the estimated standard error. (Be sure to round to the second decimal place).

i believe the correct answer is option 4.principalities were small territories that were run by russian rulers.

which statement correctly defines principalities in northern asia in the 1200s? principalities were small territories that were run by russian rulers.

hope i could ! : )

- both graphs increase on their domain.

- the graphs of both functions have the same x-intercept.

- neither graph has a y-intercept.

b, i believe, but not sure.

7.9m and 4.3°

step-by-step explanation:

let east be +x and north be +y, x = distance * cos θ, y = distance * sin θ  

for 3.5 south, y = -3.5  

for 8.2, x = 8.2 * cos 30 and y = 8.2 * sin 30  

for 15 west, x = -15  

total x = 8.2 * cos 30 – 15 ≈ -7.9  

total y = -3.5 + 8.2 * sin 30 = 0.6  

magnitude = [(8.2 * cos 30 – 15)^2 + 0.6^2)]^0.5  

the magnitude is approximately 7.9 m  

tan θ = y/x = 0.6/-7.9  

the angle is approximately 4.3˚ north of west
