Answer:
3.113, 4.507
Step-by-step explanation:
From the given values:
Mean = 3.81
Standard deviation = 1.74
Therefore
M = √(1.72/18) = 0.4
μ = M ± t(sM)
μ = 3.81 ± 1.74*0.4
μ = 3.81 ± 0.697
Recall that the mean is estimated at 90% confidence level,
Hence,
= 90% CI [3.113, 4.507]
Answer:
9) QR = 4.0
10) AC = 4.1
Step-by-step explanation:
Tan = Opps. / Adj.
9)
Tan(60) = 7 / QR
QR = 7 / Tan(60)
QR = 7 / 1.732
QR = 4.0415
QR = 4.0
10)
Tan (27) = AC / 8
AC = Tan(27) * 8
AC = 0.5095 * 8
AC = 4.076
AC = 4.1
