Answer:
Step-by-step explanation:
Given that
sample size n = 55: x bar = 654.16 and s = sample sd = 162.34
Std error = 162.34/sqrt 55 = 21.889
For 95% CI we can use t critical value as population std dev is not known.
df = 54
t critical = 2.004
Margin of error = 2.004 *21.889 = 43.866
Confidence interval lower bound = 654.16-43.866 =610.294
Upper bound = 654.16+43.866=698.026
Confidence interval rounded off at 95% = (610.29, 698.23)
Answer:
2:3 , you divide by common denominator
i guess as a decimal it might be
.50 to .75 but dont take my word for it

15
Step-by-step explanation:
a right angle is 90 degrees, so if you divide that by 6 you get one sixth of the angle
Answer:
(6,5)
Step-by-step explanation:
The slope means y travels 2 while x travels 1. So 5+1 would be x and 3+2 would be y.
