Question

Hi, can you help me answer this question please, thank you!

Answer 1

3To calculate the test statistics, we use the following steps:

Step 1: We write out the parameters

Step 2: Write out the formula for the test statistics (t)

`t=\frac{\bar{x}-\mu}{\frac{s}{\sqrt[]{n}}}`

step 3: Find t

`\begin{gathered} t=\frac{0.9-0.8}{\frac{0.58}{\sqrt[]{32}}} \\ t=(0.1)/(0.1025) \\ t=0.97532 \\ t\approx0.98 \end{gathered}`

Hence, the test statistic is approximately 0.98 to two decimal places.
