  • Introduction

    • TI-83+ and TI-84 calculator instructions are included in the text.

  • Confidence Interval for a Population Proportion

    • The second solution uses a function of the TI-83, 83+ or 84 calculators (Solution B).
    • Use the TI-83, 83+ or 84+ calculator command invNorm(0.975,0,1) to find z .025 .
    • The second solution uses a function of the TI-83, 83+ or 84 calculators (Solution B).
    • Use the TI-83, 83+ or 84+ calculator command invNorm(0.95,0,1) to find z .05 .

  • Confidence Interval, Single Population Mean, Standard Deviation Unknown, Student's-t

    • The TI-83,83+,84+ have a tcdf function to find the probability for given values of t.
    • The TI-83 and 83+ do not have the invT command.
    • The TI-83, 83+ and 84 calculators have a function that calculates the confidence interval directly.
    • The solution is shown step-by-step and by using the TI-83, 83+ and 84+ calculators. 8.6; 9.4; 7.9; 6.8; 8.3; 7.3; 9.2; 9.6; 8.7; 11.4; 10.3; 5.4; 8.1; 5.5; 6.9
    • The second solution uses the Ti-83+ and Ti-84 calculators (Solution B).

  • Notation for Poisson: P = Poisson Probability Distribution Function X ~ P(u)

    • TI-83+ and TI-84: For a general discussion, see this example (Binomial).
    • NOTE: The TI calculators use λ (lambda) for the mean.

  • Notation for the Hypergeometric: H = Hypergeometric Probability Distribution Function X ~ H (r,b,n)

    • NOTE : Currently, the TI-83+ and TI-84 do not have hypergeometric probability functions.

  • The Correlation Coefficient r

    • The correlation coefficient r is the bottom item in the output screens for the LinRegTTest on the TI-83, TI-83+, or TI-84+ calculator (see previous section for instructions).

  • Reciprocity

    • Consider the very simple network shown in figure 8.3.
    • In large populations, usually most actors have no direct ties to most other actors, and it may be more sensible to focus on the degree of reciprocity among pairs that have any ties.
    • Here, two such ties (A to B and B to A) are a reciprocated structure among the six possible ties (AB, BA, AC, CA, BC, CA) or a reciprocity of .333.
    • Analysts usually focus, instead, on the number of ties that are involved in reciprocal relations relative to the total number of actual ties (not possible ties).
    • That is, of all the relations in the graph, 69% are parts of reciprocated ties.
