Answer:
This is a false statement.
Step-by-step explanation:
This is a false statement because 35 is not 6 times greater than 7 even though their sum is 42. Therefore, this cannot be true.
Answer:
it 7/8 I just use photo math if you don't me try it hope this help
Answer:
Probability that the sample variance exceeds 3.10 is less than 0.05%.
Step-by-step explanation:
We are given that a process produces batches of a chemical whose impurity concentrations follow a normal distribution with a variance of 1.75.
Also, a random sample of 20 of these batches is chosen.
The probability distribution that we will used here is of Chi-square distribution, i.e.;
~
where,
= sample variance
= population variance = 1.75
n = sample of batches = 20
So, probability that the sample variance exceeds 3.10 is given by = P(
> 3.10)
P(
> 3.10) = P(
>
)
= P(
> 59.62) = P(
> 59.62) = Less than 0.05%
From chi-square table we can observe that Probability that
is greater than is less than 0.05%.
So, the probability that the sample variance exceeds 3.10 is less than 0.05%.
