Answer: The value of is 36.
Step-by-step explanation:
Given expression:
To find the value of at b= 5, we need to substitute the b=5 in the expression, we get
Therefore, the value of is 36, when b=5.
Answer:
Option b. should not be rejected
Step-by-step explanation:
We are given that the contents of a sample of 26 cans of apple juice showed a standard deviation of 0.06 ounces.
We have to test whether the variance of the population is significantly more than 0.003, i.e.;
Null Hypothesis, :
=
Alternate Hypothesis, :
The test statistics used here for testing variance is;
T.S. = ~
where, s = sample standard deviation = 0.06
n = sample size = 26 cans
So, Test statistics = ~
= 30
So, at 5% level of significance chi square table gives critical value of 37.65 at 25 degree of freedom. Since our test statistics is less than the critical so we have insufficient evidence to reject null hypothesis.
Therefore, we conclude that null hypothesis should not be rejected and variance of population is 0.003.
