Which of the following statement(s) is (are) correct?


Options :

6406532041749. Type II error is the probability of accepting the Null hypothesis when it is not
true.

6406532041750. The probability of accepting the null hypothesis when it is false is equal to the
power of the test.

6406532041751. The probability of rejecting the Null hypothesis when it is true is called the
level of significance.

6406532041752. If the P-value of a test is 0.04, then the corresponding test will reject the null
hypothesis at the significance level of 0.03.

A manufacturer produces cotter pins and claims that the probability of a randomly selected cotter
pin being defective is 0.3. However, an analyst suspects that the claimed probability value is too
high and decides to verify it by conducting a test. The analyst randomly selects 8 cotter pins from
the manufacturer’s production line and inspects them for defects. If less than 2 cotter pins are
defective (out of those 8 cotter pins), then the analyst rejects the claim, or else he accepts it.

A company has provided insurance policies to several people whose age is normal with variance
36. An insurance agent of the company has claimed that the average age of policyholders who are
insured through her is 30 years. We suspect that this is too low. To test the agent’s claim, we have
selected a random sample of 100 policyholders who purchased their policies through her. If the
average age of the selected 100 policyholders is greater than 31.1 years, we reject the claim;
otherwise, we accept it.

An urn contains some blue balls and some red balls. Shalini claims that if a ball is picked randomly
from the urn, then the probability p that the ball will be blue is 0.2.
Suspecting that 0.2 is too high, Nandan decided to pick 10 balls randomly. If two or more blue
balls are picked out of those 10 balls, then he accepts Shalini’s claim or else he rejects it.

An urn contains some blue balls and some red balls. Shalini claims that if a ball is picked randomly
from the urn, then the probability p that the ball will be blue is 0.2. Suspecting that 0.2 is too high,
Nandan decided to pick 10 balls randomly. If two or more blue balls are picked out of those 10
balls, then he accepts Shalini’s claim or else he rejects it.

Suppose the number of deceased people in a week because of a deadly disease in a country has
the Poisson(λ) distribution. A researcher wants to estimate λ. From studies in other countries, prior
mean should be 3, and the prior standard deviation 1. He decides to use the Gamma(α, β) prior
that matches his prior mean and standard deviation. The number of deceased people recorded
over the next 10 weeks are: 3, 5, 7, 0, 1, 7, 4, 9, 6, 4.
