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.
Answer:
y = 2
x + 9
Step-by-step explanation:
(* ̄3 ̄)╭
P-value approach is used to take a decision to reject or accept the null hypothesis as indicated below:
<span>REJECT the hypothesis, if p-value </span><span>FAIL TO REJECT the hypothesis, if p-value > the alpha value.
</span><span>Alpha value represents the level of significance </span>
<span>If alpha value is NOT indicated: alpha = 0.05 can be assumed </span>
<span>REJECT the hypothesis, because p-value (0.036) < the alpha value assumed which is 0.05</span>
Answer:
x > 10
Step-by-step explanation:
Given
x - 3 > 7 ( add 3 to both sides )
x > 10
