Answer:
Now we just take square root on both sides of the interval and we got:
For this case we can conclude that the true deviation at 90% of confidence is between 734.783 and 1657.489
Step-by-step explanation:
The confidence interval for the population variance is given by the following formula:
The sample deviation is s=1007.4542
The degrees of freedom are:
The confidence is 0.90 or 90%, and the significance would be and , and the critical values are:
Replacing the info given we got:
Now we just take square root on both sides of the interval and we got:
For this case we can conclude that the true deviation at 90% of confidence is between 734.783 and 1657.489
