I have completed the first set of answers for the mean, sum of squares, variance, and standard deviation. Unless you want to double check but this has to be correct to complete the other questions. I am confident they are right, but I am not understanding how to complete the rest. The video lecture is not helpful at all.

Fluctuations Price $0.51 $0.55 $0.63 $0.74 $0.89 $0.91 $1.01 $1.05 $1.12 $1.33 Use Excel spreadsheet from Lesson L01b to calculate and report the following values: Mean - 0.87 Sums of squares = 0.63 Variance = 0.07 Standard deviation = 0.27 NOTE: Please round all values to 2 decimal places. When rounding, remember that you would only add 1 to your second decimal place if your third decimal place is greater than or equal to 5. Question 2 3.5 pts When determining whether or not transactions are fraudulent, Ameritrade has asked that you keep their most recent policy in mind. Ameritrade has instituted a policy in which firms with prices within -68% of the normal distribution of scores are ignored, outside ~68% (but within ~95%) of the normal distribution of scores are monitored, and outside -95% of the normal distribution of scores are restricted. This policy is based on the most recent fraudulent activities that took place at Firm X. Provide the cutoff values you would use to ignore, monitor, or restrict trade for Firm A based on the recent policy implemented by Ameritrade. Use the numeric values in the following graphic as a guide. HINT: You will need to use the mean and standard deviation from the previous question and the 68-95-99 rule to create these cutoffs. $_(2)_ 5 _ ( b ) S_ (c ) S_(d)_ s_ ( @ )_ S_ (0) _ S ( 8 ) (a): (b): (d): (e).
