The claim is that for a smartphone carrier's data speeds at airports, the mean= 17.00 mbps. the sample size is n = 20 and the test statistic is t = 1.874

The null and alternative hypotheses are:

We are given that the test statistic is:

Also we are given the sample size

Now we have to find the t critical value at 0.05 (assumed) significance level for

Using the t distribution table, we have:

Conclusion: Since the t statistic does not lie outside the t critical values, therefore, we fail to reject the null hypothesis and conclude that there is sufficient evidence to support the claim that a smartphone carrier's mean data speed at airports is 17.00 Mbps.
