Answer:


And the interval would be:

Step-by-step explanation:
For this problem we have the following dataset given:
44 32.8 59.2 31.4 12.7 68.5 84.7 72.5 55.7
We can find the mean and sample deviation with the following formulas:


And replacing we got:


The confidence interval for the mean is given by:

The degrees of freedom are:

The confidence would be 0.98 and the significance
then the critical value would be:

Ad replacing we got:


And the interval would be:
