Answer:
Critical Value
Step-by-step explanation:
The critical value separates the region of rejection from the region of non rejection.
We define critical values as:
- Critical value helps us to give the decision rule for the rejection or acceptance of null hypothesis.
- Critical value separates the acceptance region from the rejection region.
- These are referred to as cut-off values that define regions where the test statistic is unlikely to lie.
- The critical value depends on the kind of test being performed and the significance level.
Answer:
The probability that the diameter falls in the interval from 2499 psi to 2510 psi is 0.00798.
Step-by-step explanation:
Let's define the random variable, 
"Comprehensive strength of concrete". We have information that 
is normally distributed with a mean of 2500 psi and a standard deviation of 50 psi (or a variance of 2500 psi). In other words, 
.
We want to know the probability of the mean of X or 
that falls in the interval ![[2499;2510]](https://tex.z-dn.net/?f=%5B2499%3B2510%5D)
. From inference theory we know that :
Now we can find the probability as follows:
Where 
, then:
