Answer:
7 ^ 6x + 2 = 7^15
taking log on both the sides
log 7^6x + 2 = log 7^15
6x + 2 log 7 = 15 log 7
log 7
F(x)=5*2
the f(x) stands for a normal X like any other algebraic equation. so all it is, is 5 times 2, which is 10.
so,
f(x)=5*2
f(x)=10<span />
Answer:
Step-by-step explanation:
a)
Confidence interval in less than symbol expressed as
Where is sample mean and is margin of error.
b)
The given t interval is
That is and
Solve these two equation by adding together.
Solve this value of \bar{x} in equation and solve for
Best point estimate of
Best point estimate of margin of error = 0.193
c)
Since sample size = 100 which is sufficiently large (Greater than 30) , it is no need to confirm that
sample data appear to be form a population with normal distribution.
