Hello

I am struggling to calculate f(m-x bar)2 and other question mentioned below

This table shows the distribution of winning times in the Kentucky Derby (a horse race) over 90 years.

Kentucky Derby Winning Times, 1930 to 2019 (seconds)
From		To	f
119		120	1
120		121	5
121		122	20
122		123	27
123		124	16
124		125	11
125		126	5
126		127	3
127		128	2
Total			90

Click here for the Excel Data File (a) Fill in the highlighted cells in the table below. (Round your answers to 2 decimal places and round standard deviation to 4 decimal places)

(b) State whether the following statement is True or False? The raw data would show us the years when the winning times were much longer than the average.

multiple choice 1

• True

• False

(c-1) Do you think it likely that the distribution of times within each interval might not be uniform? multiple choice 2

• Yes

• No

(c-2) This distribution appears to be: multiple choice 3

• Symmetric

• Skewed right

• Skewed left
