Can I please have help on the following problem? Thank you.

24. In one area, monthly incomes of technology related workers have a standard deviation of o = $650. It is believed that the standard deviation of monthly incomes of non-technology workers is higher. A sample of 71 non-technology workers are randomly selected and found to have a standard deviation of s = $800. At a 5% significance level, does the data provide evidence that the standard deviation of the incomes of non-technology workers is greater than $650? INCLUDE ALL STEPS IN THE TEST. (10 points)
