Answer: a) (176.76,172.24), b) 0.976.
Step-by-step explanation:
Since we have given that
Mean height = 174.5 cm
Standard deviation = 6.9 cm
n = 50
we need to find the 98% confidence interval.
So, z = 2.326
(a) Construct a 98% confidence interval for the mean height of all college students.
(b) What can we assert with 98% confidence about the possible size of our error if we estimate the mean height of all college students to be 174.5 centime- ters?
Error would be
Hence, a) (176.76,172.24), b) 0.976.
Answer:
Step-by-step explanation:
The given equation is :
We need to find the value of x.
When the exponent 2 removes from LHS, it will shift to RHS as square root as follows :
We know that, 4×4= 16 and 5×5 = 25
So,
So, the solution of the given equation is 4/5.
