Answer:

-1.010

Explanation:

The formula for calculating the test statistics is expressed as:

[tex]t=\frac{\frac{\overline{x}-\mu}{\sigma}}{\sqrt[]{n}}[/tex]

Given the following parameters

Mean x = 6.2

Standard deviation σ = 3.43

μ = 6.7

n = 48

Substitute the given parameters into the formula:

[tex]\begin{gathered} t=(\frac{\frac{6.2-6.7}{3.43}}{\sqrt[]{48}}) \\ t=\frac{-0.5}{0.495077} \\ t=-1.0099 \\ t=-1.010 \end{gathered}[/tex]

This shows that the test statistics rounded to 3 decimal places is -1.010
