Question

One of the Continuous Random Variables characteristics is: “The probability of one specific value is equal theoretically to zero”.

True

False

To test the following hypothesis:

H_o: µ ≥ 23

H₁: µ < 23

For a sample: x̅​​​ =22, σ =5, n=40 and α=0.05

Using t-test, the test conclusion is “Reject H_o”

True

False

To test the following hypothesis:

H_o: µ ≤ 23

H₁: µ > 23

For a sample: x̅​​​ =25, σ =5, n=40 and α=0.05

Using z-test, the test conclusion is “Reject H_o”

True

False
