Question 1: Available on MyStatLab.

Question 2:
Two polls (each based on a random sample of 1000) released just before the recent Ontario provincial election seemed to suggest conflicting outcomes.
The breakdown in percentages for the two polls were:
Liberal PC NDP Green
Angus Reid 33% 36% 26% 5%
Ekos 37.7% 31.5% 23.3% 5.9%

(a) Test at the .05 level of significance whether the data constitute evidence of a real overall disagreement between the two polls.

(b) In particular, test whether the data constitute evidence of a real disagreement between the levels of support for the PC party between the two polls. Use the
.05 level of significance. AnswerOij | Liberal | PC | NDP | Green | Row Totals | Angus Reid | 330 | 360 | 260 | 50 | 1000 | Ekos | 377 | 315 | 233 | 59 | 984 | Column Totals | 707 | 675 | 493 | 109 | 1984 |

a) Test of homogeneity

H0: No real overall disagreement between the two polls
HA: H0 is not true. There is a real overall disagreement between two polls

α = 0.05 df = (r-1)*(c-1) = (2-1)(4-1) = 1*3 = 3

For df = 3; chi-square, based on 0.05 level = 7.8417

Expected observation = Row Total*Column Total/Grand Total

Eij | Liberal | PC | NDP | Green | Row Totals | Angus Reid | 356.3508 | 340.2218 | 248.4879 | 54.93952 | 1000 | Ekos | 350.6492 | 334.7782 | 244.5121 | 54.06048 | 984 | Column Totals | 707 | 675 | 493 | 109 | 1984 |

    The problematic scenario is when the physical sequence has a loop. In this scenario, a switch which is attached to the middlebox literally cannot identify the middlebox segment based on the combination of the input interface and packet header fields. To address this scenario, SIMPLE introduce a ProcState tag that encodes the packet’s processing state inside the packet header fields using either VLAN tags, unused fields in the IP headers i.e., IP ToS fields or MPLS labels depending on the fields supported in the SDN-enabled switches. Therefore, SDN controller installs tag addition forwarding rules at the first switch of each middlebox segment, which is based on packet header fields and input ports of the switch. In addition, downstream switches consider these tags for the matching purpose and perform respective forwarding action. This process continues until the middlebox segment is finished.…
