Test statistic t rounded to two decimals

Historically, the average time it takes Jessica to swim the 200 meter butterfly is 148.4 seconds. Jessica would like to know if her average time has changed. She records her time on 50 randomly selected occasions and computes the mean to be 147.8 seconds with a standard deviation of 2.3 seconds.

The hypotheses to be tested are:

Ho mu=148.4 vs. Ha: mu not equal 148.4
