Can you please help me with my homework

Need to show all your work to get full credit. No WORK, NO CREDIT For the following dada set find the followings: (Note: need to do appropriate estimations 100 pts Total) 1. b) Median (2 pt) d) Range (2 pts) h) Coefficient of variance (5 pts) c) Mode (1 pt) a) Mean (5 pt) e) Mid-Range (2 pt) ) z-score of 2.5(5 p) 0 Variance (8 pt) D Percentile of data value 2.5 (5 pts) g) Stand. Deviation (2 pt) of data values that fall in 1.7 standand deviations from the mean (5 pt) n) Interval that contains at least 65% of the data values. (8 pts) P The Semi-Quartile Range (2 pts) n) All quartiles (8 pts) q) Construct the box plot and analyze the shape of the distribution (8 pts) s) If the data value 8.5 were in your sample set, would it be usual or unusual? o) The Inter-Quartile Range. (2 pts) r) Find the boundaries of usual nmbers (3 pts) 2 pts) ) Find outliers if any (Notei any answer you give must be based on computation.) (8 pts) u) Compute the variance by using range rule of thumb (7 pts) v) 25% Trimmed Mean (5 pts) 0.9, 1.1, 1.5, 1.7, 1.8, 1.8, 1.9, 2.5, 2.6, 2.9,6.8, 7.9 arranged form.

Answer 1

a)

The mean is

b)

There are 12 data values so median will be average of 6th and 7th data values. So median is

c)

Mode is the data value with highest frequency. That is mode is 1.8.

d)

Range =Maximum - Minimum = 7.9 - 0.9= 7.0

e)
