Answer:
A) Mean = 1264
Standard deviation = 37
B) CI ≈ (1241, 1287)
Step-by-step explanation:
A) Mean = Σx/n
Σx = 1229 + 1257 + 1243 + 1194 + 1268 + 1316 + 1275 + 1317 + 1275
Σx = 11374
Mean(x¯) = 11374/9
Mean(x¯) ≈ 1264
Standard deviation = √(∑(x - x¯)²/(n)
From online calculator;
Standard deviation; s ≈ 37
B) Our distribution factor is; DF = n - 1 = 9 - 1 = 8
From t-table attached, our critical value at 90% Confidence interval is t = 1.86
Formula for confidence interval is;
CI = x¯ ± t(s/√n)
CI = 1264 ± 1.86(37/√9)
CI = 1264 ± 22.94
CI ≈ (1241, 1287)

Answer:
53.1°
Step-by-step explanation:
Let x represent the wangle of elevation from B to C
Reference angle = x
Opposite side to x = 16 - 4 = 12
Adjacent = 9
Apply trigonometric ratio to find x.
Thus:
(nearest tenth)
Angle of elevation from B to C = 53.1°
Answer:
We get that the 165.1% of 333 is 333 • 1.651 = 549.78
Step-by-step explanation:
1. They are asking for the 165.41%
2. So, we need to multiply 333 by the representation of 165.1% in decimal by doing the multiplication using a calculator
