Key Concepts

One-Sided Test

A one-sided (or one-tailed) test is utilized when the alternative hypothesis predicts a particular direction of deviation from the null hypothesis. In this instance, it is used because the objective is to verify whether the cable Internet speed is not just different, but specifically higher than 3 Megabits per second.

Null Hypothesis (H0)

The null hypothesis represents the default claim or assumption that there is no difference or effect. In the context of testing the mean speed, it states that the cable Internet connection speed is equal to 3 Megabits per second, meaning there is no evidence of the speed being higher than this benchmark.

Alternative Hypothesis (H1)

The alternative hypothesis challenges the default claim and represents what the researcher is aiming to support. For this test, it asserts that the mean speed is greater than 3 Megabits per second, thereby indicating a one-sided test since the interest is only in speeds that exceed the specified threshold.
