Answer:

B) μD = 0.60 ± 0.10(1.397)

Step-by-step explanation:

The confidence interval is given by:

$MD±t_{\alpha/2, n-1} \frac{s}{\sqrt{n} }$

Where

MD=60

n=9

df=n-1=8

$t_{\alpha/2, n-1}=1.397$

$s=\sqrt{0.09} =0.3$

Then the confidence interval is

μD=0.60±1.397*(0.3/√9)

μD=0.60±0.10*(1.397)
