It can also be used to compare respondents’ responses to two or more questions or items. These questions‚ hiwever‚ must be meausred using the same scale.( Likert scale) Example of research question: Is there a change in confidence scores over the three time periods?

The mean results were as follows: S1=1.73 S2=12.3 K or DF=4 T= - .9148 T critical assuming a 95% accuracy=2.776 Since -.9148 < 2.776 the team rejected the null hypothesis (see table 1) After the T-test scores had been calculated‚ the team calculated the F-Ratio for the four different groups.

Intelligence Homework 2 search strategies Q1. A. Show that DFS generates about O(bm) nodes in the search tree. m: The maximum length of any path in the state space b: The branching factor: maximum number of successors of any node. At the worst case‚ DFS generates about O(bm) nodes in the search tree. As follows : At m (max depth )tries : 1 +b + b2 + b3 +….+ bm =O(bm) ‚ the graph below illustrates this. B. Explain why DFS requires less memory than BFS. In BFS you keep all nodes in memory

hypothesis that might explain why young adults are more likely to experience crime than older adults might be related to the type of housing they live in. 66.5% of young adults were more likely rented property than 30.8% of older adults (x2 = 3137.875‚ df = 1‚ p < 0.001 – Table8). Thus‚ data showed that there was a relationship between tenure and age; young adults were more to likely live in private rented accommodation and less likely own property than older people.

Assume a= .1 Some of his students take a random sample of students and comes with a 90% CI of (.80‚ .90) Based on these results‚ what will the results of Mr. Baird’s test be? Explain.
