Question

In a newspaper's survey of 510 people, 51.6% said that we should replace passwords with biometric security, such as fingerprints. The accompanying statistical display results from a test of the claim. What type of hypothesis test is being conducted here?

a) Is the test two-tailed, left-tailed, or right-tailed?

Choose the correct answer from the options below:

Two-tailed
Left-tailed
Right-tailed

Answer 1

The type of hypothesis test being conducted here is a two-tailed test.

Step-by-step explanation:

The type of hypothesis test being conducted here is a two-tailed test.

A two-tailed test is used when there is no specific direction of the alternative hypothesis. It tests for the possibility of a difference in either direction.

In this case, since the alternative hypothesis is that the percentage of people who support replacing passwords with biometric security is not equal to 51.6%, it is a two-tailed test.
