Given information
The population's average delay is minutes, with a maximum variance of minutes.
The sample average is minutes, with a -minute standard deviation.
Additional testing of the average delay claim.
Step-by-step explanation
Step 1.
We can utilize the t-distribution because the sample size is small and extra data on the average latency is provided. The t-distribution equation is as follows.
The sample standard deviation and sample size are denoted by and , respectively.
Therefore, the t-distribution can be used because the sample standard deviation, sample size, and sample average are all known, and the population average can be determined.
