The test statistic TS can be calculated using the equation:

[tex]TS=\frac{\mu-\mu_0}{\sigma/\sqrt[]{n}}[/tex]

Where μ is the sample mean, μ₀ is the null hypothesis mean, σ is the standard deviation and n is the sample size. From the problem, we identify:

[tex]\begin{gathered} \mu=0.58 \\ \mu=0.50 \\ \sigma=0.5 \\ n=674 \end{gathered}[/tex]

Using those values on the equation above:

[tex]TS=\frac{0.58-0.50}{0.5/\sqrt[]{674}}=4.15[/tex]
