Part b:
The five-number summary and draw a box plot for each of the two data sets for the given table which gives average sales tax rate in six east coast and six western states.
East coast states | Western states | ||
Florida | 6.8% | California | 8.25% |
Massachusetts | 6.25% | Arkansas | 1.76% |
Maryland | 6.00% | Oregon | 0% |
New Hampshire | 0% | Washington | 8.92% |
New York | 8.49% | Arizona | 8.25% |
Rhode Island | 7.00% | Utah | 6.76% |
Refer explanation.
Part c:
The standard deviation for each of the two data sets for the given table which gives average sales tax rate in six east coast and six western states.
East coast states | Western states | ||
Florida | 6.8% | California | 8.25% |
Massachusetts | 6.25% | Arkansas | 1.76% |
Maryland | 6.00% | Oregon | 0% |
New Hampshire | 0% | Washington | 8.92% |
New York | 8.49% | Arizona | 8.25% |
Rhode Island | 7.00% | Utah | 6.76% |
Part d:
The standard deviation for each of the two data sets using range rule of thumb for the given table which gives average sales tax rate in six east coast and six western states.
East coast states | Western states | ||
Florida | 6.8% | California | 8.25% |
Massachusetts | 6.25% | Arkansas | 1.76% |
Maryland | 6.00% | Oregon | 0% |
New Hampshire | 0% | Washington | 8.92% |
New York | 8.49% | Arizona | 8.25% |
Rhode Island | 7.00% | Utah | 6.76% |
Part e:
To compare: The two data sets in terms of their center and variation for the given table which gives average sales tax rate in six east coast and six western states.
East coast states | Western states | ||
Florida | 6.8% | California | 8.25% |
Massachusetts | 6.25% | Arkansas | 1.76% |
Maryland | 6.00% | Oregon | 0% |
New Hampshire | 0% | Washington | 8.92% |
New York | 8.49% | Arizona | 8.25% |
Rhode Island | 7.00% | Utah | 6.76% |
The average of sales tax rate in east coast states and western states are almost same. Variation is more in western states.

- Q1: A: Let M and N be two subspace of finite dimension linear space X, show that if M = N then dim M = dim N but the converse need not to be true. B: Let A and B two balanced subsets of a linear space X, show that whether An B and AUB are balanced sets or nor. Q2: Answer only two A:Let M be a subset of a linear space X, show that M is a hyperplane of X iff there exists ƒ€ X'/{0} and a € F such that M = (x = x/f&x) = x}. fe B:Show that every two norms on finite dimension linear space are equivalent C: Let f be a linear function from a normed space X in to a normed space Y, show that continuous at x, E X iff for any sequence (x) in X converge to Xo then the sequence (f(x)) converge to (f(x)) in Y. Q3: A:Let M be a closed subspace of a normed space X, constract a linear space X/M as normed space B: Let A be a finite dimension subspace of a Banach space X, show that A is closed. C: Show that every finite dimension normed space is Banach space.arrow_forwardpls helparrow_forwardpls helparrow_forward
