Step-by-step explanation:
Given that:
Our linear approximation will be of the form y = c + mx. Use the values of f at the point a and the nearby point a h to find a good approximation. (You will need to set up a linear system involving c, m,a, h, f(a), f(a+ h), where c and m are the variables. You should also be able to solve this linear system exactly for the vector.
Answer:
Value of test statistics = 2.30
Step-by-step explanation:
We are given that for a sample of 35 items from a population for which the standard deviation is 20.5, the sample mean is 458.
Also, Null Hypothesis, :
= 450
Alternate Hypothesis, :
450
The test statistics that will be used here is One sample t-test statistics;
T.S. = ~
where, = sample mean = 458
s = sample standard deviation = 20.5
n = sample of items = 35
So, test statistics = ~
= 2.30
Therefore, the value of test statistics is 2.30 .
