Answer:
t must be greater than 5.0
Step-by-step explanation:
P ( t ) = 1050e^0.16t
We want P(t) > 2337
2337 < 1050e^0.16t
Divide each side by 1050
2337/1050< 1050/1050 e^0.16t
Take the natural log of each side
ln (2337/1050)) < ln(e^0.16t )
ln (2337/1050) < 0.16t
Divide by .16
ln (2337/1050)/.16 < 0.16/.16t
ln (2337/1050)/.16 < t
5.00049<t
Answer:
(12.1409, 14.0591
Step-by-step explanation:
Given that Tensile strength tests were performed on two different grades of aluminum spars used in manufacturing the wing of a commercial transport aircraft. From past experience with the spar manufacturing process and the testing procedure, the standard deviations of tensile strengths are assumed to be known.
Group Group One Group Two
Mean 87.600 74.500
SD 1.000 1.500
SEM 0.316 0.433
N 10 12
The mean of Group One minus Group Two equals 13.100
standard error of difference = 0.556
90% confidence interval of this difference:
t = 23.5520
df = 20
